What is the branch of science that is devoted to understanding how plants and animals arise from single cells?

Developmental biology

What is the term for the process where male and female gametes fuse to form a fertilized egg?

Fertilization

In which region of the embryo do cells divide more slowly due to the presence of yolk?

Vegetal hemisphere

What is the name given to the ball or sheet of similar cells formed during cleavage divisions?

Blastula

What is the term for the process where cells divide rapidly and involve no growth, resulting in daughter cells half the size of the mother cell?

Cleavage

What is the process that converts the original cell mass into a three-layered structure?

Gastrulation

Which layer gives rise to the outer layer of the body's organs?

Ectoderm

What process is responsible for the formation of extraembryonic structures for support and nutrition?

Gastrulation

Which science studies the effects of environmental agents on embryos?

Teratology

What is the process involving the formation of gametes in sexual reproduction?

Gametogenesis

What is the name given to the liquid-filled cavity in the center of the ball-shaped blastocyst?

Blastocoel

Which region of the embryo contains the most yolk and results in slower cell division?

Vegetal hemisphere

What term refers to the branch of science devoted to understanding how plants and animals arise from single cells?

Developmental biology

Which process involves the conversion of a single cell, the fertilized egg, into a complex organism consisting of many anatomical parts?

Embryonic development

During which process do male and female gametes fuse to form a fertilized egg?

Fertilization

What is the name given to the process that converts the original cell mass into a three-layered structure?

Gastrulation

Which type of cells are formed from germ cells in the embryo?

Germ line cells

What is the significance of the germ line in sexual reproduction?

It contains the genetic information for the future organism

Which process involves the formation of haploid (1n) chromosome set from germ cells in the embryo?
