increase in cell size through increase in organelle size and amount of cytoplasm. ex muscle and nerve cells. mainly postnatal growth

Increase in cell numbers through mitosis. Examples in postnatal growth: skin, blood capillaries, liver, adipose tissue. Mainly prenatal growth

Body grows up to a certain point (maturity) then growth stops

Growth continues throughout the lifetime. Fish

Form and function. Series of uninterrupted correlated events.

Cells becomes specialized. All cells start from the single fertilized ovum and then turn into liver cells, muscle cells, or skin cells

Establishment of shape and patterns in an animal

the study of form and structure

combining of sperm and ovum to form a zygote

Protective layer that surrounds and protects the oocyte

Cell division following fertilization. Occurs without the cell increasing so the cell size decreases

Solid ball of cells, Mulberry shaped hence the name

Cell formed during the clevage

Hollow ball with initially one cell thick layer around the cavity. during differentiation it becomes two different cell types
