Final answer:

Blastomeres are the nearly identical cells produced by early cleavages in an embryo, which eventually form the blastula during the development of multicellular organisms.

Step-by-step explanation:

The nearly identical cells that are produced by early cleavages during the development of multicellular organisms are known as blastomeres. These blastomeres are formed as the zygote undergoes a series of rapid cell divisions, a process termed cleavage. After the cleavage has produced a significant number of cells, the embryo is referred to as a blastula. This blastula consists of a spherical layer of cells, called the blastoderm, that encompasess a fluid-filled or yolk-filled cavity known as the blastocoel. Each cell within the blastula is a blastomere. This stage precedes the formation of the gastrula, where the cells rearrange themselves to form three distinct germ layers.
