OSMOSIS
OSMOSIS- is the movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, aiming to equalize the solute concentrations on the two sides.

TONICITY- refers to the relative concentration of solutes in water inside and outside the cell.
Isotonic solution
the concentration of water molecules is equal inside and outside of the
cell.
Hypotonic solution- refers to a solution that
contains less solute compared to the
cytoplasm of the cell.
Hypertonic solutionIt has higher osmotic pressure (or has more solutes) than another solution to which it is
compared.
DIFFUSION- describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. Diffusion is invoked in the social sciences to describe the spread of ideas.The time dependence of the statistical distribution
in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient.Diffusion is invoked in the social sciences to
describe the spread of ideas.

ACTIVE TRANSPORT
It requires the cell to use energy to free in and out of the cell.The pull of molecules in the process of active transport is from a region of lower concentration to a region of higher concentration
Two processes involve are:
1. Exocytosis2. Endocytosis
a. Phagocytosisb. Pinocytosis
