Which cells are involved in reproduction and are called sex cells?

The correct answer, gametes, refers to the specific types of cells that are directly involved in reproduction. Gametes are the reproductive cells that carry half the genetic information necessary for the formation of a new organism. In humans, there are two types of gametes: sperm in males and ova (eggs) in females. During fertilization, the fusion of these gametes results in the formation of a zygote, which has a complete set of chromosomes.

Somatic cells, on the other hand, are the non-reproductive cells that make up the majority of the body’s tissues and organs. These cells contain a full set of chromosomes and do not participate in the reproductive process.

Stem cells are undifferentiated cells with the potential to develop into many different cell types, but they are not specifically involved in reproduction.

Autosomal cells refer to the cells with non-sex chromosomes, which also are not involved in the reproductive process.

Thus, the term gametes is specifically designated for the sex cells responsible for reproduction, making it the accurate choice in this context.
