The largest cell in the human body is the female egg cell, also known as an ovum.
This single cell is visible to the naked eye and is much larger than other human cells.
The egg cell's size is crucial for its role in reproduction. It contains all the necessary nutrients and genetic material to support the development of a new human being after fertilization.
In contrast, the sperm cell, which is the male counterpart, is one of the smallest cells in the human body.
While the egg cell is the largest cell by volume, other cells, such as nerve cells (neurons), can be extremely long.
However, their overall volume is much smaller than the egg cell.
