Biology Question on Kingdom Plant
Meiosis in Dryopteris takes place during
A
spore formation
B
gamete formation
C
spore germination
D
zygote formation.
Answer
spore formation
Explanation
Solution
Pteridophytes like Dryopteris exhibi haplo-diplontic life cycle, where both sporophytic (2n) and gametophytic (n) phases are multicellular but sporophyte is the dominant phase. Meiosis occurs during spore formation. Haploid spores produce bisexual gametophytes which produce haploid gametes. Fertilisation occurs and haploid gametes fuse to form diploid zygote which gives rise to a new sporophyte.
