Blastomere vs. Morula

Blastomerenoun

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

Blastomerenoun

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

Blastomerenoun

any cell resulting from cleavage of a fertilized egg

Blastomere

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.

Morulanoun

(embryology) A spherical mass of blastomeres that forms following the splitting of a zygote; it becomes the blastula

Morulanoun

The sphere or globular mass of cells (blastomeres), formed by the clevage of the ovum or egg in the first stages of its development; - called also mulberry mass, segmentation sphere, and blastosphere. See Segmentation.

Morulanoun

a solid mass of blastomeres that forms when the zygote splits; develops into the blastula

Morula

A morula (Latin, morus: mulberry) is an early-stage embryo consisting of 16 cells (called blastomeres) in a solid ball contained within the zona pellucida.A morula is distinct from a blastocyst in that a morula (3–4 days after fertilization) is a mass of 16 totipotent cells in a spherical shape whereas a blastocyst (4–5 days after fertilization) has a cavity inside the zona pellucida along with an inner cell mass. A morula, if untouched and allowed to remain implanted, will eventually develop into a blastocyst.The morula is produced by a series of cleavage divisions of the early embryo, starting with the single-celled zygote.
