Where does meiosis occur in algae?
The life cycle seen in most of the algae is called the haplontic life cycle. Zygote represents the diploid sporophyte generation. The zygote undergoes meiotic division to form haploid spores and thus zygotic meiosis occurs in most algae.
Can meiosis occur in a haploid species?
Meiosis occurs in a diploid organism, not haploid.
Where does meiosis occur in Chlamydomonas?
Chlamydomonas is haploid plant. The zygospore (zygote) is formed by the fusion of gametes. The meiosis takes place in zygospore.
Which of the following undergoes meiosis in algae?
Zoospore undergoes meiosis in algae.
Where does meiosis occur in organisms?
Meiosis occurs in the primordial germ cells, cells specified for sexual reproduction and separate from the body’s normal somatic cells. In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication.
Why can’t meiosis occur in a haploid cell?
The haploid multicellular plants (or algae) are called gametophytes, because they make gametes using specialized cells. Meiosis is not directly involved in making the gametes in this case, because the organism is already a haploid. Fertilization between the haploid gametes forms a diploid zygote.
Where does meiosis take place in plants?
Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants. In angiosperms, meiosis takes place in sporogenous cells that develop de novo from somatic cells in anthers or ovules.
What is the function of Pyrenoid in Chlamydomonas?
The pyrenoid is a microcompartment within the chloroplasts of algae and hornworts. Its known function is to promote photosynthetic CO2 fixation by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco).
Which feature is not true regarding bryophytes?
(i) Bryophytes lack true roots, stem and leaves.
Is Chlamydomonas unicellular flagellated?
Chlamydomonas is an alga which is single-celled organisms I.e they are unicellular. They have two apical flagella which an alga use for transduction function and movement around in a wet environment.
