Egg cells are the biggest: you could only fit one on the head of a pin. But I'm not sure if a sperm cell is bigger than a red blood cell or vice versa.
An egg cell contains more cytoplasm and needed chemicals than a sperm cell. This is because an egg cell is larger and contains all the necessary organelles and nutrients to support early development after fertilization. Sperm cells are specialized for motility and delivering genetic material to the egg.
FERTILIZATION
A sperm fused with an egg
A sperm cell is the male reproductive cell responsible for fertilizing an egg cell during sexual reproduction. An egg cell, or ovum, is the female reproductive cell that contains genetic material and is needed for fertilization to occur.
It's a fertilized egg. It can also be called a zygote.
the egg is larger than the sperm cell
the egg is larger than the sperm cell
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.

A sperm and an egg.
The uniting is known as fertilisation of the egg by the sperm.
egg by far
Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.

A sperm cell is used to fertilize an egg from a female. The combination of the sperm and the egg produces a fertilized egg which will become a new individual.
