Mitosis

Mitosis is a process where a single cell divides into two identical cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.

chromosomes

a long strand of coiled up DNA

Active transport

It is the movement of particles against a concentration gradient

4 of 13

Diffusion

Movement of particles of a liquid or gas from an area of high concentration to an area of low concentration

Osmosis

Movement of water(not particles) from an area of high concentration to an area of low concentration

Prokaryotic Cell

A simple cell that does not have a nucleus the DNA flows free in the cytoplasm. E.G. Bacteria

7 of 13

Eukaryotic Cell

A type of cell that has a nucleus. The DNA is enclosed in the nucleus. E.G. plant and animal

Stem cells

A stem cell is a cell with the unique ability to develop into a specialized cell types in the body.

Differentiation of cells

Differentiation is the generation of specialised cell which have different organelles to enable them to carry out specific functions.

Isotonic

Concentration of solute is the SAME outside and inside.

11 of 13

Hypotonic

Concentration of solute outside is LESS than inside of the cell.
