Cell Transport

the ability of an organism to self-adjust to maintain a balance of life functions in a changing environment

substance that can dissolve another substance Ex. water

Movement of molecules from areas of low concentration to areas of high transportation that requires a cell to expend its own energy

amount of solute dissolved in a given amount of solvent

the process by which molecules of a substance move from an area of high concentration of that substance to areas of lower concentration until they are evenly distributed about the container

substance that dissolves in the solvent Ex: salt, Kool aid

a homogeneous mixture of solute(s) and solvent(s)

difference in concentration of molecules across a distance

pressure exerted on cell wall

cells shrink away from cell wall, turgor pressure lost

a solution whose solute concentration is equal to the solute concentration inside a cell

The type of solution that causes water molecules to move into the cell and the cell swells

The type of solution that causes water molecules to leave the cell, and cell shrivels up and dies.

allows the passage of some particles while blocking the passage of others

controls entry into and out of cell
