The process by which a gamete cell is produced is called meiosis. To arrive at this answer, we need to understand the different processes mentioned as options and their relation to cell division.
A. Osmosis is the movement of water molecules across a semipermeable membrane. Although osmosis is an important process for maintaining cell homeostasis, it does not directly involve cell division, so it is not the correct choice for the production of gamete cells.
B. Mitosis is the process of cell division that occurs in somatic cells, resulting in the formation of two identical daughter cells. However, mitosis does not produce gamete cells, as the daughter cells produced through mitosis retain the same number of chromosomes as the parent cell.
C. Meiosis is the correct answer for the production of gamete cells. It is a specialized form of cell division that occurs in reproductive cells, such as sperm cells (in males) and egg cells (in females). Meiosis involves two rounds of cell division, resulting in the production of four daughter cells, each with half the number of chromosomes as the parent cell. These daughter cells are the gamete cells, which are haploid (containing half the number of chromosomes) and are used in sexual reproduction.
D. Respiration is the process by which cells utilize oxygen and produce energy in the form of ATP. It is not directly related to cell division or the production of gamete cells.
In conclusion, the correct answer is C. Meiosis is the process by which gamete cells are produced.
