Where does meiosis occur in green algae?

Like Hydrodictyon, meiosis occurs inside the zygospore, which is the resting stage [See the life history of Volvox].

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.

Where does meiosis occur in plants?

In flowering plants, meiosis occurs in megaspore mother cells (megasporocytes) within the ovules of ovaries, and in microspore mother cells (microsporocytes) within the anthers of stamens.

Which of the following undergoes meiosis in algae?

Zoospore undergoes meiosis in algae.

Which one undergoes meiosis in the life cycle of algae?

Zoospores are motile spores and aplanospores are nonmotile spores produced due to mitosis in algae. A cell with 32 chromosomes undergoes meiosis.

Does meiosis occur only in plants?

It takes two rounds of division to produce four cells, each with only one copy of each chromosome (haploid). Complete answer: Meiosis is a process that happens in all animals and plants. … Meiosis creates gametes directly in mammals.

IT IS SURPRISING:  Which of the following happens in mitosis but not meiosis quizlet?

What is meiosis and where does it occur in plants and animals?

Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. … Meiosis occurs in all sexually-reproducing single-celled and multicellular organisms (which are all eukaryotes), including animals, plants and fungi. It is an essential process for oogenesis and spermatogenesis.

Where in plants does mitosis occur?

Meristems are regions in plants in which mitosis takes place. Apical meristems are at the tips of shoots and roots and contribute to increases in length. Lateral meristems are responsible for increases in girth.

Which method of reproduction takes place in algae?

Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores.

How Zoospores are formed in algae?

The zoospores are formed in reproductive body the zoosporangium. The zoospores can be biflagellate e.g., Chlamydomonas, biflagellate and quadriflagellate e.g., Ulothrix, Cladophora, multi-flagellate e.g., Oedogoniwn. Zoospores move in water before they germinate to make new plants.

How does green algae fragmentation occur?

Fragmentation occur in green algae -spirogyra. 1)the parent body breaks down into two or many pieces. 2)these pieces are called fragments.

What are the products of meiosis in the life cycle of a seed plant?

What are the products of meiosis in the life cycle of a seed plant? Megaspores or microspores. A seed includes contributions from three separate generations of plants.

What is life cycle with zygotic meiosis known as?

To return from a diploid stage to a haploid stage, meiosis must occur. In regard to changes of ploidy, there are 3 types of cycles: haplontic life cycle — the haploid stage is multicellular and the diploid stage is a single cell, meiosis is “zygotic”.

Which of the following processes occur during meiosis but not mitosis?

The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
