similarities of heteromorphic and isomorphic generation
why you fool british have founded them
alternation of generation
meiosis and mitosis
alternation of generation is very important in plants because it results into the formation of a variety of new organisms... it is also important because it provides such organisms which have more chances of survival...
sporophyte and gametophye. since plants have alternation of generation, both are multicellular (haploid and diploid)
Brown algae show a distinct alternation of generations, characterized by a multicellular sporophyte generation and a multicellular gametophyte generation. The alternation of generations allows for both asexual and sexual reproduction within the life cycle of brown algae.
a chromosomal alternation during gamete formation

Some types of algae that show a distinct alternation of generations are members of the green algae group, such as Ulva and Spirogyra. These algae have a haploid gametophyte generation and a diploid sporophyte generation. The gametophyte generation produces haploid gametes that fuse to form a diploid zygote, which develops into the sporophyte generation that produces haploid spores.
The spores produce gametophytic phase of the plant after germination to complete alternation of generation.
The name given to this life cycle is alternation of generations. In this cycle, plants alternate between a multicellular diploid sporophyte stage that produces spores and a multicellular haploid gametophyte stage that produces gametes.
