Mitosis : A form of cell division that produces two daughter cells, genetically identical to each other and to the parent cell.
Meiosis : A form of cell division that produces four genetically different daughter cells, each of which has half the number of chromosomes of the parent cell.
Cancer : Group of disorders in which certain cells lose their ability to control both the rate of mitosis and the number of times mitosis takes place.
-
Diffusion : The movement of a substance from its area of higher concentration to its area of lower concentration. (Passive process)
Active transport : The movement of a substance(usually ions) from its area of lower concentration to its area of higher concentration. (Opposite of diffusion)
Osmosis : The diffusion of water across a selectively permeable membrane, from its area of higher concentration to its area of lower concentration.
Hypotonic sol : Has a low concentration of solutes and thus a higher concentration of water than another solution.
Hypertonic sol : Has a higher concentration of solutes and thus a lower concentration of water than another solution.

Phagocytosis : Process where large particles are engulfed by the cell and become incorporated into a vacuole within the cell.
