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.

What is heteromorphic alternation of generation?

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.


What is the significance of alternation of generation?

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...


What are the two stage of the plant life cycle?

sporophyte and gametophye. since plants have alternation of generation, both are multicellular (haploid and diploid)


Which type of algae shows a distinct alternation of generations?

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.


Which mutation could be passed on to generation?

What types of algae show a distinct 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.


How are spores useful to some plants?

The spores produce gametophytic phase of the plant after germination to complete alternation of generation.


What is the name given to the life cycle of plants which includes a sporophyte generation and a gametophyte 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.
