Can meiosis occur in a haploid cell?
Organisms that are haploid, e.g. algae such as Volvox, Spirogyra, etc. show meiosis in the zygote. The haploid gametes fuse to produce a diploid zygote, which undergoes meiosis to produce haploid spores, which divide mitotically to produce gametophyte.
Can a haploid cell undergo mitosis?
Both diploid and haploid cells can undergo mitosis. … If a haploid cell undergoes mitosis, which is something certain types of plant and fungus do as part of their normal life cycles, the end result is two identical haploid cells (n→n).
Where does meiosis occur in haploid cells?
Then the four haploid cells (each with half of the parental cell chromosome) are produced through two successive divisions. Meiosis takes place only in sexually reproductive organisms. Sometimes the haploid gametes are produced which are further fused to haploid sperms depending on the type of organisms.
Where does meiosis occur in a haploid and diploid cell?
In mammals, Meiosis occurs only in gamete producing cells within the gonads. During meiosis, homologous (paired) chromosomes separate, and haploid cells form that have only one chromosome from each pair.
Is mitosis a diploid or haploid?
Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Can mitosis occur in haploid and triploid cells?
The mitotic cell division can occur in haploid n cells diploid 2n cells triploid 3n cells etc. Mitosis is a copying process that does not interfere with cell ploidy.
Where does meiosis occur?
Meiosis is the process of cells splitting into four haploid cells, thus reducing the chromosome number by half in each cell. They also give rise to gametes in the human body, but plant spores in plants. Meiosis occurs in the sex cells, so the sperm and egg cells in the human body, to create even more of themselves.
Does meiosis take place in haploid or diploid cells?
To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs.
