MCQ
Sporophytic generation is represented by zygote only in:
- AFunaria
- BChlamydomonas
- CPinus
- DSelaginella
Explanation:
Chlamydomonas belongs to the class Chlorophyceae.
These are algae which do not show a fixed mode of alternation of generation.
Hence the sporophytic generation itself is considered as the zygote.
This zygote undergoes meiotic division resulting in the formation of haploid individuals i.e. gametophyte.
Zygotic meiosis is the characteristic feature of Chlamydomonas.
