Explain alternation of generation in life cycle of Bryophyta.

Last Answer : In the life cycle of bryophytes, two types of multicellular generation ‘sporophyte’ and ‘gametophyte’ alternate with each other; the gametophyte generation gives rise to sporophyte generation and the sporophyte gives rise to gametophytes. This phenomenon is called alternation of generation.
