What Is Haplo-Diplontic Life Cycle Class 11?

What is haplo-Diplontic life cycle with example?

All the plants showing sexual reproduction alternate between two multicellular stages, viz. Haploid gametophyte and diploid sporophytes.

Difference Between Diplontic and Haplontic Life Cycle.

Diplontic Life Cycle Haplontic Life Cycle
Angiosperms, Gymnosperms, some algae such as Fucus, Cladophora, etc. Most of the algae such as Volvox, Spirogyra, etc.

What is haplo-Diplontic alternation of generation?

Haplo-diplontic type of life cycle involves the clear alternation of generations between a haploid gamete producing gametophyte and a diploid spore-producing sporophyte. Both bryophytes and pteridophytes exhibit this kind of life cycle pattern.

What is haplo life cycle?

Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. This type of life cycle is called a haplodiplontic life cycle (Figure 20.1). In haplodiplontic life cycles, gametes are not the direct result of a meiotic division.

Is Ulothrix Haplontic?

Option C) Haplontic - is the correct answer because the dominant phase of the haplontic life cycle is haploid, and the diploid phase is short, that is, when the zygote is produced by the fusion of two haploid cells. Hence, the Life cycle in Chlamydomonas, Ulothrix, Spirogyra is haplontic.
