Document Summary
Enables internal organs to grow larger and become more sophisticated: sa, volume. Act as a hydrostatic skeleton, providing support for soft-bodied animals. Consider patterns of cleavage and development in bilateral animals and how they can be used to categorize animal groups. Radial cleavage tiers or layers of cells on top of each other in early embryo. Associated w/ regulative development, where if separate each blastomere, the cell can adjust and create its own, smaller, embryo. Spiral cleavage by the eight cell stage, cleavage produces two quartets of cells that lay in the furrows in between. Unlike in radial, cells are very closely packed together. Mosaic development, organ formers become localized, if you separate cell defective larvae. Deutrorostomia: share an inherited common developmental sequence that begins with radial regulative cleavage and progresses from a blastula to a gastrula.
