What are gametes?

Gametes are specialized sex cells responsible for sexual reproduction in organisms. They include sperm cells in males and egg cells in females. In plants, male gametes are typically formed in pollen grains, while female gametes are found in ovules within the ovary of a flower. When a male gamete fertilizes a female gamete, it leads to the formation of a zygote, which further develops into a new organism. Understanding this concept is crucial, as gametes play a vital role in the genetic diversity and reproduction of both plants and animals. The other choices refer to different cell types or structures that do not involve the process of sexual reproduction.
