What is the largest cell?

The largest cell in the human body is the female egg cell, also known as an ovum. The egg cell is approximately 100 micrometers in diameter, which is visible to the naked eye. The egg cell is also one of the few cells in the body that is visible to the naked eye without the aid of a microscope.

Egg cells are produced by the female reproductive system and are responsible for carrying the genetic material of the female to be fertilized by a sperm cell from the male. Once fertilized, the egg cell develops into an embryo and eventually a fetus.

The large size of the egg cell is important for its function, as it contains all the necessary organelles and nutrients to support the developing embryo. Additionally, the egg cell is surrounded by a protective layer called the zona pellucida, which helps prevent multiple sperm cells from fertilizing the egg.
