What is Alternation of generations

– Alternation of generations is a phenomenon by which a plant exhibits two phases in its life cycle
– one phase being dominant at a time
– namely, gametophyte and sporophyte
– gametophyte is haploid (n)
– produces gametes
– sporophyte is diploid (2n)
– produces spore
– two phases alternate
– occurs in many plant groups e.g mosses and ferns
