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...

alternation of generation
meiosis and mitosis
hetero=different;so heteromorphic alternation of generation is the life cycle consists of haplophase and diplophase where they are dissimilar in size and maturization time.
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.
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.
An alternate generation is each of the two forms of an organism whose lifestyle involves alternation of generations - also known as metagenesis - the production of sexual and asexual organisms in alternate generations.
