Blastomere vs. Blastula — What's the Difference?

In biology, a blastomere is a type of cell produced by cleavage (cell division) of the zygote after fertilization and is an essential part of blastula formation.

An early embryonic form produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity. Also called blastosphere.

Any of the cells resulting from the cleavage of a fertilized ovum during early embryonic development.

(embryology) An early form in the development of an embryo, consisting of a spherical layer of cells filled with fluid; a blastosphere.

(biology) Any cell that results from division of a fertilized egg.

That stage in the development of the ovum in which the outer cells of the morula become more defined and form the blastoderm.

One of the segments first formed by the division of the ovum.

Early stage of an embryo produced by cleavage of an ovum; a liquid-filled sphere whose wall is composed of a single layer of cells; during this stage (about eight days after fertilization) implantation in the wall of the uterus occurs

Any cell resulting from cleavage of a fertilized egg
