What is diplontic life cycle


Diplontic life cycle refers to the life cycle of organisms, which is dominated by the diploid stage. Plants and algae show alternation of generation. All the plants showing sexual reproduction alternate between two multicellular stages, viz. Haploid gametophyte and diploid sporophytes.

What is a Diplobiontic life cycle?

Diplobiontic. A life cycle that involves the alternation of two multicellular phases (one haploid and another diploid) to complete sexual reproduction; also known as the 'alternations of generations' and as the diplohaplontic life cycle, e.g. mosses and ferns. Gametangia.

What is Diplontic and Haplontic?

Haplontic life cycle is that when sporophytic generation is represented by only one celled zygote and gametophyte is dominant. Example : volvox,spirogyra,chlamydomonas. 2) Diplontic life cycle is that when the gametophytic phase is represented by single to few celled haploid gametophyte and sporophyte is dominant.
