Answer:
A. They produce reproductive cells.
D. They reduce chromosome number.
Definitions
---> Meiosis is the part of the process of gamete formation, consisting of chromosome conjugation and two cell divisions, in the course of which the diploid chromosome number becomes reduced to the haploid.
---> Mitosis is the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.
---> Gamete is a reproductive cell (sperm in males or eggs in females), having only half of a complete set of chromosomes.
---> A cell contains the genetic (hereditary) information of a living being.
---> Chromosomes are any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size of X and Y for the female and male sex chromosomes respectively.
Both meiosis and mitosis are cell division processes that involve the replication and separation of chromosomes. In mitosis, a single cell divides into two identical daughter cells that have the same number of chromosomes as the parent cell. In contrast, meiosis is a two-step process that produces four haploid daughter cells from a single diploid parent cell. These daughter cells are genetically diverse and have half the number of chromosomes as the parent cell. Both meiosis and mitosis are important for reproduction and growth. Mitosis is involved in the growth and repair of tissues, while meiosis is involved in the production of gametes (sperm and eggs) for sexual reproduction. Both processes also involve the reduction of chromosome number in the daughter cells, which is necessary to maintain the correct chromosome number in the species.
