Chlamydomonas refers to kingdom Plantae and division Thallophyta, zygotic meiosis is the characteristic aspect observed in them. Thus, option A: Chlamydomonas is the correct answer. Note: The components of green algae exhibit zygotic, gametic and sporic meiosis.
In which algae does zygotic meiosis occur?
Fucus is a brown alga that follows a diplontic life cycle. Ectocarpus kelps have a haplo-diplontic life cycle. Gametic meiosis occurs in the diploid life cycle. Meiosis occurs only during gamete formation.
What shows zygotic meiosis?
Chlamydomonas has haplontic life cycle hence showing zygotic meiosis or initial meiosis. Chlamydomonas has haplontic life cycle hence showing zygotic meiosis or initial meiosis.
Which algae does not show zygotic meiosis?
Question : Zygotic meiosis is characteristic of
(d) Zygotic meiosis is represented in the haplontic life cycle of many algae including Chlamydomonas. In such a life cycle, all cells are haploid except zygote.
What organisms use zygotic meiosis?
- Zygote is the only diploid structure in the life cycle.
- The dominant individual in the life cycle is haploid hence the life cycle is haplontic.
- Meiosis takes place at the time of Zygote germination.
- This life cycle appears in all fungi and some algae.
Does meiosis occur in algae?
Either immediately or at some later time, a diploid cell directly or indirectly undergoes a special reductive cell-division process (meiosis). … In algae, as in plants, haploid cells in this stage are called gametophytes because they produce gametes.
Does Funaria show zygotic meiosis?
Zygotic meiosis is the characteristic of a) Fucus b) Funaria c) Marchantia d) Chlamydomonas. … As Chlamydomonas pertains to kingdom Plantae and division Thallophyta, zygotic meiosis is the characteristic feature observed in them.
Does Fucus show zygotic meiosis?
C) Fucus. D) Funaria. Hint: In phanerogams, sporadic meiosis is present, in which sporophyte sustains meiosis to form haploid spores. zygotic meiosis is organized in the haplontic life process, in which meiosis arises in the zygote.
Does volvox have zygotic meiosis?
Generally, their life histories are haplontic. I represent them here by Pediastrum, Hydrodictyon, Volvox, Chlamydomonas, and Oedogonium. Colonial taxa are multicellular and quite distinctive in their appearance. … These have zygotic meiosis and, therefore, have a haplontic life history.
Does zygotic meiosis occur in Chlamydomonas?
Zygotic meiosis occurs in chlamydomonas. When the zygote divides meiotically or when zygote undergoes reduction division after division of nucleus i.e. after karyogamy it is called as zygotic meiosis.
What is the difference between green brown and red algae?
The main difference between red brown and green algae is that red algae contain chlorophyll a, chlorophyll d, and phycoerythrin, while brown algae contain chlorophyll a, chlorophyll c, and fucoxanthin and green algae contain chlorophyll a, chlorophyll b, and xanthophylls.
