Which algae shows Haplodiplontic life cycle?

Which algae shows Haplodiplontic life cycle?

– Volvox is a green alga which can be classified under thallophyta. From the description above, we see that seven plants mentioned in the question fall under the category of bryophytes or pteridophytes and exhibit a haplo-diplontic life cycle while the other 4 belong to either gymnosperms or thallophytes.

Which group of plants exhibit Haplodiplontic life cycle?

Haplo-diplontic life cycle involves the alternation of generations between a haploid gametophyte and a diploid sporophyte. Bryophytes and pteridophytes exhibit this life cycle.

What do you mean by Haplobiontic life cycle?

Filters. (biology) Describing a plant or fungus that has only either a haploid or a diploid, (but not both!) phase in its life cycle. That is, it lacks any alternation of generations.

What are the two phases of life cycle?

Explanation: Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures.

Does Chlamydomonas show Haplodiplontic life cycle?

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.

Does algae show haplontic life cycle?

Name an alga which is (a) Hapiodiplontic (b) Diplontic. Answer: Haplo diplontic type of life cycle is exhibited by Ectocarpus, Polysiphonia and Kelps.

What is the definition of a haplodiplontic life cycle?

Adjective. haplodiplontic (not comparable) (biology, of a life cycle) Having multicellular diploid and haploid stages. Beside above, what is life cycle of an organism? A life cycle is defined as the developmental stages that occur during an organism’s lifetime.

When does the gametophyte stage of the haplontic life cycle occur?

During the germination, the zygotes are meiotically divided into haploid (n) zoospores, which are then developed into haploid plants. This is known as the gametophyte (haploid) stage. The haplontic life cycle is also known as the monogenic life cycle.

What is the haplodiplontic life cycle in ferns?

The haplodiplontic life cycle is also known as the diplohaplontic or diplobiontic. This type of life cycle is noticed in the ferns there is regular alternation between a sporophytic generation and the gametophytic generation. The fern plant represents the diploid sporophyte which undergoes asexual reproduction and produces haploid spores.

Which is the diplobiontic stage of the algae life cycle?

There are three-phase in Diplobiontic Type such as Haploid gametophyte, Diploid carposporophyte, and Diploid tetrasporophyte. Are Sporophytes haploid? A sporophyte (/sp??ro??fa?t/) is the diploid multicellular stage in the life cycle of a plant or alga.
