Which term is the female sex cell?

• A. Egg
• B. Sperm
• C. Zygote
• D. Embryo

Answer: (A)

Gametes are the cells used in sexual reproduction, and they come in two types: eggs from females and sperm from males. The female sex cell is the egg because it is produced by the ovaries and carries the female’s genetic material, along with the cytoplasm and organelles needed to support early development after fertilization. Sperm is the male gamete, a zygote is the single cell formed when sperm and egg unite, and an embryo is the developing organism after implantation. Therefore, the female sex cell is the egg.
