Cell Specialization

Cells being specialized to perform specific functions

Do all cells have the same DNA

Yes its just that different genes are activated

Stem Cells

Stem Cells are cells that havnt gone through cell differentiation and can become any cells. Found in bone marrow

Gene Expression

A process in which a gene is switched on or off resulting in different proteins being made. Causes cell differentiation

Neurons (nerve cells)

sends info from one part of the cell to the other

Long and thin

Sperm cell

fertilizes the egg for reproduction
