What is facilitated diffusion
Involves 2 types of protein; channel proteins and carrier proteins. From an area of higher concentration to an area of lower concentration
PASSIVE PROCESS

What is osmosis
The net movement of water molecules across a selectively permeable membrane from a region of low solute concentration to a region of high solute concentration
PASSIVE PROCESS

What does hypertonic mean
Greater solute concentration
6 of 12
What does hypotonic mean
Lower solute concentration
7 of 12
What does isotonic mean
The same solute concentration
8 of 12
What is active transport
The movement of ions and molecules against the concentration gradient. Energy is required so ACTIVE PROCESS
9 of 12
What is bulk transport
This type of transport involves materials entering or leaving a cell without actually crossing a membrane
10 of 12
What is endocytosis in bulk transport
The cell membrane folds around the material which then enters the cell inside a vesicle
11 of 12
What is exocytosis in bulk transport
Refers to substances being moved out of the cell, where vesicles fuse with membrane
