Question

Difference between zoospore and zygospore

Answer 1

ZOOSPORE ZYGOSPORE A motile flagellated asexual spore, as of certain algae and fungi. Also called swarm spore. A zoospore is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these spores are created by some algae, bacteria and fungi to propagate themselves. A zoosporangium is the sexual structure in which the zoospores develop in a plant, fungi, or protists (such as the oomycota) A large multinucleate spore formed by union of similar gametes, as in algae or fungi. A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists. Zygospores are created by the nuclear fusion of haploid cells. In fungi, zygospores are termed chlamydospores and are formed after the fusion of hyphae of different mating types. In many eukaryotic algae, including many species of the Chlorophyta, zygospores are formed by the fusion of unicellular gametes of different mating types.

Answer 2

A zygospore is a product of sexual reproduction by fusion of contents of two similar gametangia. It is found in all orders of green algae, Zygomycetes fungi and group of phycomycetes. It is diploid and a thick walled resting spore.

Zoospore is motile having one, two or more flagella. It can be found in green brown algae and some phycomycetes. It is haploid and is a naked spore produced within sporangium.
