Question

explain about blastomere and gastrula
class11# ..​

Answer 1

Answer:

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.

gastrula is a developmental stage of some animal embryos in which different germ layers are present.

sorry for giving half answer...

Answer 2

Explanation:

blastomere: any cell that results from division of a fertilized egggastrulation

gastrulation is a phase early in the embryonic development of most animals, during which the blastula (a single-layered hollow sphere of cells) is reorganized into a multilayered structure known as the gastrula. Before gastrulation, the embryo is a continuous epithelial sheet of cells; by the end of gastrulation, the embryo has begun differentiation to establish distinct cell lineages, set up the basic axes of the body (e.g. dorsal-ventral, anterior-posterior), and internalized one or more cell types including the prospective gut.
