Hint: A zygospore is the product of sexual reproduction formed by the fusion of two similar gametangia. Zoospores is the asexual motile spores which uses flagella for locomotion. A cell of fungi and algae formed by the fusion of two similar gametes is known as zygospore.
What is zygospore and zoospore?
As nouns the difference between zygospore and meiospore is that zygospore is (botany) a zygosperm while meiospore is a haploid spore produced by meiosis.
As nouns the difference between zygospore and spore is that zygospore is (botany) a zygosperm while spore is a reproductive particle, usually a single cell, released by a fungus, alga, or plant that may germinate into another.
Is zygospore and zygote same?
Zygote is the structure formed as a result of fertilization under favorable conditions, it divides and grow up to the fungus. Zygote under unfavorable conditions secrete thick and may be spiny in some fungal species to cope these conditions and called Zygospore.
A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists. … When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released. In fungi, a sporangium is produced at the end of a sporangiophore that sheds spores.
Where is zygospore found?
The more primitive aquatic and terrestrial fungi tend to produce zoospores. The zoospores of aquatic fungi and funguslike organisms swim in the surrounding water by means of one or two variously located flagella (whiplike organs of locomotion). Zoospores produced…
Why is zygospore called resting spore?
Explanation: In Algae and Fungi, the haploid gametes fuse to form a diploid zygote. It does not germinate immediately to produce sporophyte. It secretes a thick wall around to become a resting spore called zygospore.
What is the difference between zoospores and Oospores?
As nouns the difference between zoospore and oospore is that zoospore is a motile asexual spore of some algae and fungi while oospore is (biology) a fertilized female zygote, having thick chitinous walls, that develops from a fertilized oosphere in some algae and fungi.
What is the example of zoospore?
An asexual spore with a flagellum used for locomotion but lacking a true cell wall. Examples of organisms producing zoospores are some algae, fungi and protozoans.
What is a zoospore Class 12?
Complete answer: A zoospore is a spore that is motile in nature. They are asexual animals, as they give rise to new individuals without sexual fusion. They are naked and wall-less cells. They use flagella for locomotion. The flagella also help to swim in aquatic habitats for correct dispersal.
Is Zoospore a zygote?
Differentiate Between a Zoospore and a Zygote Zoospores are the asexual spore seen in some of the species like plants and algae. Zygotes are sexually produced diploid cells, Formed by the fusion of two haploid cells. … Zygotes are non-motile in nature as they don’t have flagella for locomotion.
What is Zoospores Ncert?
Zoospores are asexual spores that are motile in nature. They use flagella for locomotion. They are the means of asexual reproduction.
How does zygote differ from Zoospore in terms of ploidy?
A zygote is a non-motile diploid cell formed as a result of fertilization. It is formed as a result of sexual reproduction. Zoospores are produced when the organism is reproducing by asexual mode of reproduction. … Zoospores are haploid flagellated cells.
What is Zoospores in biology?
A zoospore is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these spores are created by some protists, bacteria, and fungi to propagate themselves.
What is the structure of a zygospore?
Zygospores generally have a large store of food reserves and a thick, resistant cell wall. Following an appropriate environmental stimulus, such as a change in light, temperature, or nutrients, the zygospores are induced to germinate and start another period of growth.
What is the major feature of Glomeromycetes?
The glomeromycetes do not reproduce sexually and cannot survive without the presence of plant roots. They have coenocytic hyphae and reproduce asexually, producing glomerospores.
What is primary zoospore?
Two types of zoospores are produced: The primary zoospore, which is posteriorly biflagellated, is released from the zoosporangium, encyst and germinates to form the secondary zoospore which is reniform (=bean-shaped) and laterally flagellated. … Youngest zoosporangium has dense protoplasm with basal septum.
What is zoospore formation?
Gene Ontology Term: zoospore formation The process in which a diploid cell undergoes meiosis, and the meiotic products acquire specialized features of asexual motile mononucleate flagellated spores called zoospores.
Is zoospore present in bryophytes?
A) motile spores seen in bryophytes. B) motile sexual spores. The zoospores swim after liberation, then suspend their flagella, encyst and ultimately germinate into green growth. …
Why does a zygospore have a coat with thick walls?
The developing diploid zygospores have thick coats that protect them from desiccation and other hazards. They may remain dormant until environmental conditions are favorable. When the zygospore germinates, it undergoes meiosis and produces haploid spores, which will, in turn, grow into a new organism.
What is the difference between zoospore and Aplanospore?
Zoospores and aplanospores are two types of spores produced by algae and fungi during asexual reproduction. … The main difference between zoospores and aplanospores is that zoospores are motile spores whereas aplanospores are nonmotile spores.
Is the zygospore diploid or haploid?
During mating, two haploid parent cells fuse, forming a diploid spore called a zygospore. The zygospore is genetically different from the parents.
What does zygospore mean in science?
Definition of zygospore : a thick-walled spore of some algae and fungi that is formed by union of two similar sexual cells, usually serves as a resting spore, and produces the sporophytic phase.
What is zoospore short?
Definition of zoospore : an independently motile spore especially : a motile usually naked and flagellated asexual spore especially of an alga or lower fungus.
What is the difference between zygote and Oospore?
As nouns the difference between oospore and zygote is that oospore is (biology) a fertilized female zygote, having thick chitinous walls, that develops from a fertilized oosphere in some algae and fungi while zygote is a fertilized egg cell.
What is the difference between Zoospores and conidia?
Zoospores and conidia are asexual structures found in algae and fungi, respectively. Both are haploid cells present in the tips of their hyphae. Zoospores possess flagella; hence, they are motile. In contrast, conidia are non-motile, and they do not possess flagella.
