Q
what are the steps of gastrulation?
A
- cleavage occurs and splits zygote into numerous smaller cells (blastomeres)
- blastomeres reorganize to form a hollow cavity (blastocoel), cluster of cells now a blastula
- vegetal end folds inward to create 2 distinct layers: ectoderm and endoderm, separated by matrix
