Q.Differentiate between a zoospore and a zygote.

Zoospore:

• A zoospore is a microscopic, motile structure used for asexual reproduction, commonly found in aquatic fungi and algae (e.g., Chlamydomonas).
• It typically bears flagella, which allow it to swim through water.
• It is produced directly from the parent organism (by mitotic division), without the involvement of gamete formation or fertilisation.
• It can directly develop/germinate into a new individual, without needing to fuse with any other cell.
• Being formed asexually, zoospores are usually genetically identical to the parent.

Zygote:

• A zygote is the cell formed as a result of fertilisation — the fusion of a haploid male gamete with a haploid female gamete, during sexual reproduction.
• It is typically diploid (2n), since it results from the combination of two haploid (n) gametes.
• Unlike a zoospore, it is non-motile in most cases (in animals and plants) and cannot directly become a free-living organism instantly — it must undergo further developmental processes (embryogenesis: cleavage divisions and differentiation) to develop into a mature new organism (embryo → offspring).
• Being the product of the fusion of two different gametes, the zygote (and the individual it develops into) is genetically distinct from either parent. …

Compare origin (asexual mitotic product vs sexual fusion product), ploidy (usually haploid vs diploid), motility (often motile/flagellated vs typically non-motile), and developmental f …

• Assuming a zoospore is a type of gamete — it is an asexual propagule, not involved in fertilisation.
• Missing the ploidy distinction (zoospore is generally haploid; zygote is diploid). …
