Question explain in detail:
Explain alternation of generations in the life cycle of an organism. Use an example from the plant kingdom and discuss how that group of plants (Gymnosperm, Angiosperm, etc.) accomplishes reproduction by alternation of generations.
Ans.All the stages through which an organism passes from zygote of one generation to the zygote of next generation constitute its lifecycle.
The life cycles of sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations .
