IPA: //ˈblæstəˌmɪr//
KK: /ˈblæstəˌmɪr/
A type of cell that forms during the early stages of development after a fertilized egg divides.
The blastomeres continue to divide and eventually form a structure called the morula.
Blastomere → It is formed from "blasto-" (from Greek "blastos", meaning germ or sprout) and "-mere" (from Greek "meros", meaning part). The word refers to a part of a germ or sprout, specifically a cell formed by the division of a fertilized ovum.
Think of 'blasto-' meaning a germ or sprout, and '-mere' meaning a part — a blastomere is a part of the germ or sprout formed during early development.
