Question

Alternation of generation in bryophytes with illustration​

Answer 1

Answer:

The life-cycle of a bryophyte shows regular alternation of gametophytic and sporophytic generations. This process of alternation of generations was demonstrated for the first time in 1851 by Hofmeister. Thereafter in 1894 Strasburger could actually show the periodic doubling and halving of the number of chromosomes during the life-cycle.
