egg cell
The egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile).

Why cells are generally small in size?

Complete answer:

Cells are so little so that they can maximize their ratio of area to volume. Smaller cells have a better ratio which allows more molecules and ions to be manipulated across the cell membrane per unit of cytoplasmic volume. … That’s why cells are so small.
