Which of the following statements are true about reproduction through spore formation in Rhizopus stolonifera or black bread mold? A. Spores grow on dry surfaces B. Spores are covered by thin walls C. Spore formation in Rhizopus takes place inside its hyphae. D. The offspring that germinate from spores have DNA identical to that of their. The versatile mode of reproduction in fungi is also responsible for their vast occurrence. Take the example of fungal reproduction by formation of spores. The spores are lightweight and disperse easily from one place to another, through wind, water, or other agents. In favorable conditions, the fungal spores germinate and develop into new fungi

Spore Formation Fun Scienc

  1. Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction
  2. Vegetative reproduction occurs through fragmentation, asexual occurs through formation of spores and binary fission, whereas sexual reproduction takes place by fusion of two haploid gametes. Some algal species can reproduce by more than one means depending upon the environmental conditions. Here's more about the reproductive process in algae
  3. g, special reproductive hyphae known as sporangiophores are produced. * Compared to sexual reproduction, asexual reproduction is more common in fungi given that it allows for the rapid spread of the organisms. * Some spores are produced in the sporangium (sac) through mitotic division (e.g. conidia)
  4. Spores are the asexual reproductive bodies. Spores are not seeds. In the spore formation method of reproduction, the parent plant produces hundreds of tiny spores in spore cases. When the spore case of the plant bursts, then the spores spread into air
  5. Sexual reproduction takes place by fusion of two nuclei originating from two individuals of opposite mating types, generally designated as male and female. Fusion of the nuclei is preceded by fusion of two protoplasts; the process is called plasmogamy. Fusion of the nuclei is known as karyogamy
  6. ate to give rise to new organisms
  7. The fore spore increases in size, which becomes opaque and highly refractive, called the endospore. The entire process of sporulation takes place within 16 to 20 hours. The cell in which spore is formed, called sporangium, which remains viable for short period of time after maturation of spore. The spore is liberated by autolysis of sporangium

5. SPORE FORMATION. Spore formation is the asexual method of reproduction. The reproduction by spore formation takes place in plants. In spore formation, the parent plant produces hundreds of microscopic reproductive units called 'spores'. When the spore case of the plant bursts, then the spores spread into air Spore formation: Many non - flowering plants reproduce through spore formation, spore are tiny cells protected by a thick wall. Fungi such as bread moulds reproduce asexually using this method. Question 3. Explain what you understand by sexual reproduction Name one organism which reproduces by spore formation. Answer. Asexual reproduction through budding takes place in : (i) Amoeba and Yeast In Spirogyra, asexual reproduction takes place by: (a) division of a cell into two cells (b) breaking up of filaments into smaller bit

Spore Formation Class 10, How do organism Reproduc

(iii)Fragmentation:It is a form of asexual reproduction where a new organism is formed from the fragments of the parent body. It is the only mode of asexual reproduction in Spirogyra. (iv)Spore formation:Many non-flowering plants reproduce through spore formation. Spores are tiny cells protected by a thick wall Reproduction in yeast takes place by . A) zygote done clear. B) fragmentation done Spore formation done clear. D) all of the above In the carpel, the male gamete makes its way to the female gamete bypassing down through the _____. A) Ovary done clear. B) Pollen tube done. Genetic material is transferred from one generation to the next as a result of reproduction through DNA copying. DNA copying takes place with high constancy and considerable variations, that is, advantages to the species for stability in the changing environment. Question 10. Describe sexually transmitted diseases and mention the ways to. Fig. 12.7 Reproduction through spore formation in fungus Fig. 12.8 Reproduction through spore formation in fern The spores are asexual reproductive bodies. Each spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity. Pollination takes place in plants with the help of wind.

Which of the following statements are true about reproduction through spore formation in Rhizopus? Choose 2 answers: Spores are covered by thick walls. The offsprings that germinate from spores have DNA identical to that of their parent. Spores grow on dry surfaces. Spore formation in Rhizopus takes place inside its hyphae In which of the following organisms does spore formation take place? [A] Mucor [B] Planaria [C] Spirogyra [D] Potato; The method of asexual reproduction in spirogyra is... [A] division of a cell into two cells [B] breaking of filaments into smaller bits [C] division of a cell into many cells [D] formation of a large number of bud The most common mode of asexual reproduction is through the formation of asexual spores, which are produced by one parent only (through mitosis) and are genetically identical to that parent. Spores allow fungi to expand their distribution and colonize new environments Sexual reproduction takes place with slight variations in different groups of plants. Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures

bi) Asexual spore formation takes place at the ends of specialised structures called conidiophores. A random number of nuclei is divided into individual cells with thickened cell walls as a protective coat. Just like in sexual reproduction, the spores break off and are dispersed A spore is a unit of reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. This sums up as, not only can an organism reproducing through spores can reproduce in normal condi.. Asexual spore formation, however, most often takes place at the ends of specialized structures called conidiophores. What is the purpose of Zygosporangium? Reproduction in Zygomycota Fusion of two hyphae leads to the formation of a zygosporangium, a thick-walled structure that is capable of surviving environmental extremes Asexual reproduction occurs by forming a specific type of spores. In this process, some cells or protoplasm of few cells of the plant divide to create a small-sized structure, the spore. Each spore is germinated and liberated from the mother cell and gives rise to a new plant. It generally takes place by the following method The seed is covered by a seed coat, which is derived from the female sporophyte. Seed development takes another one to two years. Once the seed is ready to be dispersed, the bracts of the female cones open to allow the dispersal of seed; no fruit formation takes place because gymnosperm seeds have no covering

Whereas sexual reproduction is common in mycelia under adverse environmental conditions, they also produce through fragmentation (a type of asexual reproduction) under favorable conditions. Spore formation is the most common mode of reproduction in fungi and allows them to spread and colonize new environments Most ferns reproduce through spores found underneath leaves. When mature, the spores explode and release a dark brown, dust-like substance. When this comes in contact with warm and moist soil, the process of reproduction begins. When the humidity, light and temperature is ideal, new fern plants grow. The conspicuous fern plants are the sporophytes

The sexual reproduction takes place by the fusion of male and female gametes by the process called fertilization to form zygote. Fertilisation (Zygote formation) Sexual reproduction (fertilization) in plants The different steps that take place during sexual reproduction in plants are. The pollen are deposited on stigma and begins to germinate Question.39 (a) What is spore formation? (b) Draw a diagram showing spore formation in Rhizopus. (c) List two advantages for organisms to reproduce themselves through spores. Answer. (a) When a slice of bread is kept in moist dark place for a few days, spores of Rhizopus present in air settle on the bread to form new fungus plants of Rhizopus

CBSE Class 7 Science Reproduction in Plants MCQs, Multiple

Asexual reproduction occurs through the fragmentation of colonial and filamentous algae or by spore formation (as in fungi). Spore formation takes place by mitosis. Binary fission also takes place (as in bacteria). During sexual reproduction, algae form differentiated sex cells that fuse to produce a diploid zygote with two sets of chromosomes. Vegetative Reproduction in Rhizopus. Sometimes the thallus of the Rhizopus breaks accidentally or due to some other factors into the few fragments, after which each fragment give rise to a new thallus on favourable conditions. Asexual Reproduction in Rhizopus. The asexual reproduction can take place through both sporangiospores and chlamydospores During spore formation a structure called sporangium develops from the fungal hyphae. The nucleus divides several times within the sporangium and each nucleus with a small amount of cytoplasm develop into a spore. Asexual reproduction takes place through budding in. (a) amoeba (b) Yeast (c) plasmodium (d) Leishmania Answer: (b) Yeast.

Describe a simplistic model of endospore formation. 1) spore septum begins to isolate newly replicated DNA 2) plasma membrane starts to surround replicated DNA 3) a double membrane forespore forms (precursor to the endospore) 4) peptidoglycan layer forms between the 2 membranes 5) spore coat forms 6) endospore is released (a) The sexual reproduction takes place after considerable accumulation of food material and the climax of vegetative activity is over. (b) The bright light is the major factor for the production of the gametes. (c) A suitable pH value is required. (d) The optimum temperature is necessary. Parthenogenesis Some fungi also produce spores, which can scatter and grow into new organisms.asexual reproduction in fungi may take place through spore formation conidiophore,by budding etc. Hom Vegetative reproduction is a type of asexual reproduction found in plants. This type of reproduction occurs when new individuals are formed without the production of seeds or spores. The formation of new plants out of rhizomes or stolons is an example of vegetative reproductive, such as in the strawberry plant

Asexual reproduction takes place in the following ways. therefore, it is a type of asexual reproduction. VI. Spore Formation (Sporulation): Since plants produced through micro propagation (tissue culture) are genetically identical, they show genetic uniformity. (v) Vegetative propagation by plant tissue culture (micro propagation) has. (iii)Fragmentation:It is a form of asexual reproduction where a new organism is formed from the fragments of the parent body. It is the only mode of asexual reproduction in Spirogyra. (iv)Spore formation:Many non-flowering plants reproduce through spore formation. Spores are tiny cells protected by a thick wall There are many advantages, if an organism reproduces through spores. Advantages of spore formation: Large numbers of spores are produced in one sporangium. Spores are distributed easily by air to far-off places to avoid competition at one place. Spores are covered by thick walls to prevent dehydration under unfavourable conditions The spores, or fungal seeds, formed by asexual reproduction are called conidia, and this process allows the fungus to reproduce more quickly than sexual reproduction alone. All Ascomycota fungi. Asexual reproduction takes place through budding in [NCERT] (a) Amoeba (b) Yeast (c) Plasmodium (d) Leishmania Answer: (b) Asexual reproduction in Hydra and yeast takes place by budding. Spore Formation. An individual divides into no. of small spores, each spore giving rise to new individual

It is the type of reproduction in which the reproducing plants give rise to clones of itself. This type of reproduction may take place naturally or can be induced artificially. Artificial means include grafting, cutting, layering, naturally by means of runners, suckers, bulbs, etc. Spore Formation [Image will be uploaded soon In sexual reproduction, a haploid spore grows into a haploid gametophyte. If there is enough moisture, the gametophyte is fertilized and grows into a diploid sporophyte. The sporophyte produces spores, completing the life cycle. Asexual methods of reproduction include apogamy, poliferous frond tips, and rhizome spreading Specific cells take part in reproduction. 2. Technique. Techniques of reproduction are simple. Techniques of reproduction are commonly complex. 3. Asexual Reproduction. It occurs through fission, budding and spore formation. It occurs by several methods like fragmentation, regeneration, budding, spore formation, vegetative reproduction, etc. 4 Fungus - Fungus - Sexual reproduction: Sexual reproduction, an important source of genetic variability, allows the fungus to adapt to new environments. The process of sexual reproduction among the fungi is in many ways unique. Whereas nuclear division in other eukaryotes, such as animals, plants, and protists, involves the dissolution and re-formation of the nuclear membrane, in fungi the.

In protozoa, reproduction takes place by asexual (involving mitosis) and sexual (involving meiosis); however, some reproduce asexually only. Asexual Reproduction : Asexual reproduction involves the mitotic cell division of parent body into two or more young individuals that develop into nature organisms Fern Spores. Fern is a common name for the cryptogamous, or spore-producing, plants belonging to the division Filicophyta, also called Filicinophyta. They are primitive vascular plants with true roots, stems, and complex leaves. Most ferns reproduce through the alternation of generations, alternating successive generations of sexual and asexual.

Which of the following can show somatogenic reproduction

Fungi on bread and plants such as moss and ferns reproduce through spores. Fragmentation: In this process, a new organism is developed from the fragments of the parent body. Example, An alga. 8. Name one organism which reproduces by spore formation. Answer. Protozoa reproduces through spore formation. 9. Name the method by which Paramecium reproduces. Is this method sexual or asexual? Answer. Parameciumreproduces by the method of fission and it is a method of asexual reproduction. 10. Name two plants : (a) which can be grown from.

We can say that vegeatative reproduction also occurs in rose, then why is it necessity of flower in it? Then here is the answer: In vegetative repr.. Spore formation is a method of asexual reproduction in which the parent plant produces hundreds of tiny spores, which can grow into new organisms under favourable conditions. Question 27. Describe how growth of fungus on a piece of moist slice of bread takes place. Answer: Take a slice of moistened bread

Spore formation; Fragmentation; Question 3. How does an embryo get nourishment inside the mother's body? (2011 OD) Answer: After implantation, a disc-like special tissue develops between the uterus wall and the embryo called placenta. The exchange of nutrients, oxygen and waste products between the embryo and the mother takes place through. Asexual Reproduction. In asexual reproduction new plants are obtained without production of seeds or spores. Vegetative propagation. It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds. Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts. Can a starfish become two? Starfish are capable of asexual reproduction, which means one starfish can create another one without mating The formation of such spores that is due to sporulation provides a multilayered structure to the amoeba that can be maintained for a long time, maybe for months of harsh conditions. Spores are designed to protect an amoeba from extreme dryness, heat, and intense radiation for a long time, relative to the normal life span of the microorganism Very Short Answer Type Questions: Answer: When a single parent is involved and gamete formation does not take place in reproduction, this is called asexual reproduction. Answer: When a unicellular organism divides to produce two daughter organisms, this process is called binary fission. Answer: When a unicellular organism divides to produce.

Asexual reproduction of many plants is effected by the formation of motile or nonmotile spores. In lower plants, special spores of asexual reproduction are formed either endogenously, usually within sporangia (in algae and lower fungi), or exoge-nously, on the surface of branches of the thalli, or conidio-phores (in higher fungi) In human males, the testes lie in the scrotum, because it helps in the. (a) process of mating. (b) formation of sperms. (c) easy transfer of gametes. (d) secretion of estrogen. Answer. Answer: b. 23. There is a greater possibility for the evolution of a new species in organisms which reproduce by Variations in organisms occur through: (a) vegetative reproduction is (b) asexual reproduction (c) sexual reproduction (d) spore formation Answer: (c) sexual reproduction. Question 19. Transfer of pollen grains trom pollen sac to stigma is called: (a) pollination (b) ovulation (c) fertilization (d) none of these Answer: (a) pollination. (i) Spore formation in Rhizopus: This is an asexual method of reproduction in bacteria and fungi. Spores are unicellular bodies formed by cell division in a parent organism. After detaching from the parent, and if conditions are suitable, they germinate directly or indirectly into a new individual

So morphologically reproduction is Isogamous. However, at the time of conjugation male gamete become active and motile and female gamete passive and non-motile, so physiologically reproduction is Anisogamous. In Spirogyra sexual reproduction is of two type. i) Scalariform: It take place between the cells of two different filaments of opposite. Fig. 12.7 Reproduction through spore formation in fungus Spore formation In Chapter 1 you learnt that the fungi on a bread piece grow from spores which are present in the air. Repeat Activity 1.2. Observe the spores in the cotton-like mesh on the bread. When spores are released they keep floating in the Fig. 12.8 Reproduction through spore. Fig. 24.4 Spore formation in Chlamydomonas successively to form 4 to 8 spores. Spores are also formed for reproduction in fungus, moss and fern. Spores are single cells which upon their release from the parent plant develop into new individuals (figure 24.4). (ii) Asexual reproduction in plant

20. Which of the following statements are trueabout ..

SPORULATION (SPORE FORMATION) This is when organisms reproduce by means of spores. A spore is a single haploid cell that is capable of directly growing into a new organism. It consists of a nucleus and a thin cytoplasm. They are resistant to harsh conditions and can germinate when conditions are favourable 4. Spore Formation in Plants. The spore is an asexual reproductive body. They are light in weight and are capable of covering long distances in a short time. The spores have a hard protective layer which helps them survive extreme conditions. Under suitable conditions, the spore develops into a new organism by germination. Moss and Ferns are. 4. Spore formation. 1. Vegetative Propagation. It is the formation of new plants from vegetative units of bud, stem, etc. These vegetative units are called propagules. Vegetative reproduction may take place using various plant parts as given below. (i) Vegetative Reproduction by Stem. The stems or branches of plant normally bear buds in the. Spore formation takes place inside the macrocyst, from where the resulting haploid spores will be released. Sexual reproduction is most likely to take place in very damp conditions. In drier conditions, cellular slime molds enter an asexual reproductive phase. Haploid ameboid cells cease feeding and clump together to form a slug-like.
