Which statement is true for all sexually reproducing plants and animals?
The process of mitosis always produces diploid cells. |
The process of meiosis produces haploid cells. |
The process of mitosis produces gametes. |
The process of meiosis produces gametes. |
The process of meiosis produces diploid cells. |
The correct answer is The process of meiosis produces haploid cells.
Explanation: Meiosis occurs during the sexual life cycle of all eukaryotes. Meiosis is divided into three categories depending on when this process occurs during the sexual cycle and these are gametic meiosis, sporogenic meiosis, and zygotic meiosis.
In gametic meiosis type, meiosis occurs during the gametes (haploid) formation.
In the case of sporogenic meiosis, haploid spores are produced by meiotic division from the cells of sporophyte (diploid). These haploid spores divide mitotically and generate the gametophyte (haploid). Cells of the gametophyte produce gametes through the process of mitosis.
In zygotic meiosis type, meiosis occurs after diploid zygote formation. In this case, meiosis produces haploid cells, not gametes. These haploid cells then divide mitotically.
