Cell Membrane |
Also called plasma membrane. Separates intracellular (inside the cell) material from extra cellular (outside the cell) material. |
|
|
Permeable |
Having pores or holes that permit the movement of water and substances |

Phagocytosis |
Eating of pathogens or cellular disease |
|
|
Passive Transport |
Transport process that requires NO energy in the form of ATP |
|
|
Active Transport |
Transport process that DOES require energy (ATP) to move a substance from an area of low concentration to an area of high concentration
|
|
|
Diffusion |
The movement of a substance from an area of higher concentration to an area of low concentration. (Breathing) (most common) |
|
|
Equilibrium |
The point at which no further net diffusion occurs |
|
|
Facilitated diffusion |
A form of diffusion that is responsible for the transport of many substances (helper) |
|
|
Osmosis |
Diffusion of water (solvent) from an area with more water to an area with less water (pulling pressure) |
|
|
Tonicity |
The ability of a solution to affect the volume and pressure within a cell |
|
|
What 3 terms are used to illustrate tonicity? |
Isotonic, Hypotonic, hypertonic |
|
|
Endocytosis |
A transport mechanism that involves the intake of food or liquid by the cell membrane |
|
|
What are the two forms of endocytosis |
Phagocytosis (eating) Pinocytosis (drinking) |
|
|
Pinocytosis |
A type of endocytosis whereby the cell membrane ingests water (cellular drinking) |
|
|
Exocytosis |
Moves substances out of the cells |
|
|
Apoptosis |
Cell death or cell suicide |
|
|
