What are gametes?

• A. Sex cells involved in reproduction.
• B. Body cells that form organs.
• C. Cells that contain two sets of chromosomes.
• D. Cells that lack genetic material.

Answer: (A)

Gametes are the reproductive sex cells involved in the formation of offspring. They are haploid, carrying one complete set of chromosomes, and are produced by meiosis to ensure genetic variety. When a sperm fertilizes an egg, their haploid sets combine to form a diploid zygote with the full chromosome number, enabling development. In humans, gametes have 23 chromosomes each. The other descriptions refer to different cell types or states—body or somatic cells are diploid and form organs, while cells that lack genetic material are not gametes.
