Blastula Definition:
During the development of most animals, cleavage leads to the formation of a multicellular stage called a blastula, which in many animals takes the form of a hollow ball.

Blastula Notes:
The blastula is a hollow sphere of cells which are referred to as blastomeres. They surround an inner fluid-filled cavity called the blastocoel formed during an early stage of embryonic development in animals. Embryo development begins with a sperm fertilizing an egg to become a zygote which undergoes many cleavages to develop into a ball of cells called a morula. Only when the blastocoel is formed does the early embryo become a blastula. The blastula precedes the formation of the gastrula in which the germ layers of the embryo form.
