Document Summary

Protostomes develop mouth first from blastopore, anus develops from another region, determinate cleavage, spiral cleavage: deuterostomes develop anus first from blastopore, mouth develop from another region, indeterminate cleavage, radial cleavage aa. Epiboly movement of cells for physical restructuring through thinning and spreading cell layers during gastrulation bb. Involution size reduction of organ (e. g. uterus retract after childbirth) cc. Invagination folding of outer layers to form pocket in surface (blastula invagination) dd. Ectoderm outer germ layer that develops into skin, nervous system (attractoderm) ee. Mesoderm middle germ layer that develop into musculoskeletal system, cardiovascular system, connective tissue ff. Endoderm inner germ layer develop into lining digestive, respiratory system gg. 2. essential during early cleavage: protein synthesis is essential because it controls the period of rapid cell division, mrna synthesis is not essential since cleavage uses materal mrna for essential protein synthesis during early cleavage. Actinomycin d does not arrest early amphibian cleavage but blocks.
