Final answer:
The statement is true; gametes, which are sperm in males and eggs in females, develop from germ cells within the gonads through a process known as spermatogenesis for sperm and oogenesis for eggs.
Step-by-step explanation:
The statement that gametes arise from germ cells in the gonads is indeed true. Gametes are the sex cells that are involved in reproduction and are haploid in nature, which means they contain half the genetic material of a regular body cell. In humans, gametes consist of sperm in males and eggs in females. The process of forming sperm is known as spermatogenesis, which takes place within the seminiferous tubules of the testes, and the process of forming eggs is called oogenesis, occurring in the ovaries. Germ cells, which are diploid, undergo meiosis to produce these haploid gametes. The male gonads, known as the testes, are held outside the body cavity in a muscular sac called the scrotum, while the female gonads are the ovaries.
