Question
Explain briefly the alternation of generation in bryophytes.
✓
Answer
Bryophytes show alternation of generation. The main plant body is gametophyte. After fertilisation of egg and spermatozoids, zygotes do not undergo reduction division and they produce a multicellular body called sporophyte. Then some cells undergo division and produce haploid spores which germinate to produce gametophyte.
