Definition: A single cell formed by the fusion of a sperm and an egg cell.
Number of cells: One.
Appearance: Microscopic, spherical, clear membrane, central nucleus.
Fertilized egg/zygote:
Definition: A fertilized egg, also known as a zygote, is a single cell formed by the fusion of a sperm and an egg cell. It contains the complete genetic information needed to develop into a new individual.
Number of cells: A zygote has one cell. It begins to divide rapidly shortly after fertilization, becoming a blastocyst (a hollow ball of cells) within about 5-7 days.
Appearance: A zygote is microscopic, measuring only about 0.1-0.2 millimeters in diameter. It is a spherical cell with a clear membrane and a central nucleus.
