AP Bio Chapter 36

The succession of rapid cell divisions without significant growth during early embryonic development that converts the zygote to a ball of cells.

• Cleavage 
• Cleavage Furrow 
• Morphogenesis 
• Mesoderm 

When an egg is fertilized by more than one sperm.

• allocation
• nitrification
• anchorage
• polyspermy

An animal embryo at the early stage of development when it is a hollow ball of cells.

• centralization
• typosperm
• blastula
• gastrulation

The fluid-filled cavity of a blastula.

• blastocoel
• sperm
• endoderm
• speciation

The development of the form of an organism and its structures

• coloration
• hyperextension
• morphogenesis
• trophoblast

In animal development, a series of cell and tissue movements in which the blastula-stage embryo folds inward, producing a three-layered embryo, the gastrula

• autoimmunity
• biocatalysis
• abscission
• gastrulation

An embryonic stage in animal development encompassing the formation of three layers: ectoderm, mesoderm, and endoderm.

• binary fission
• gastrula
• cryobiology
• chromate

the innermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the lining of the gut and associated structures.

• endoderm
• denaturation
• efferent
• foetus

The outermost of the three primary germ layers in animal embryos; gives rise to the outer covering and, in some phyla, the nervous system, inner ear, and lens of the eye

• expressitivity
• genome
• ectoderm
• hadron

The middle primary germ layer in a triploblastic animal embryo; develops into the notochord, the lining of the coelom, muscles, skeleton, gonads, kidneys, and most of the circulatory system in species that have these structures.

• epithilial
