Process by which molecules or ions scatter or spread spontaneously from regions of high to low concentration

Diffusion

1

Carrier molecules transport substances across membranes from a region of high concentration to low concentration

Facilitated diffusion

2

Movement of water through a selectively permeable membrane from a high to low concentration of water

Osmosis

3

The amount of pressure needed to stop osmosis

Osmotic pressure

4

A solution with the same osmotic pressure

Isotonic

5

A solution with the lower osmotic pressure than the solution which it is compared to

Hypotonic

6

A solution with greater osmotic pressure than the solution with it is compared

Hypertonic

7

Move particles from a region of low concentration to high concentration; requires energy

Active transport

8

Cell membrane envelops a substance and draws it into the cell in a vescicle

Endocytosis

9

Transport of substances out of a cell in membrane bounded vescicles

Exocytosis

10

Process by which a cell engulfs and digests solids

Phagocytosis

11

Process by which a cell engulfs droplets of fluid from it's surroundings

Pinocytosis

12

Same shape that communicates with other similar shapes that let's certain particles through

Receptor meditated Endocytosis
