It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation.
A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte). It once was called hydrogen power.
In more simple terms, it is a life cycle in which there is both a multicellular diploid form, and a multicellular haploid form.
meiosis and mitosis
The phenomenon in which one generation of certain plants and animals reproduces asexually, followed by a sexually reproducing generation. Also known as alternation of generations.
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.
..It best describe the tubtub
The spores produce gametophytic phase of the plant after germination to complete alternation of generation.
similarities of heteromorphic and isomorphic generation
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.
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)
a chromosomal alternation during gamete formation
The phenomenon in which one generation of certain plants and animals reproduces asexually, followed by a sexually reproducing generation. Also known as alternation of generations.
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.
