Flashcards in Cell Transport Deck (11):
0

Isotonic

When the concentration of solutes outside and inside the cell is equal

1

Hypotonic

The solution with the lesser concentration of solute

2

Hypertonic

The solution with the greater concentration of solute

3

Active transport

Movement of particles against a concentration gradient
Requires ATP

4

Passive transport

The movement of particles from an area of higher concentration to an area of lower concentration
Doesn't require ATP

5

Osmosis

Diffusion of water across a selectively permeable membrane

6

Diffusion

Movement from higher concentration to lower concentration

7

Facilitated diffusion

Transports larger ions and polar molecules
Channel proteins and carrier proteins

8

Carrier proteins

Specific shape, protein movement brings molecules in to cell

9

Cell membrane

Most important in maintaining homeostasis

10

Turgor pressure

pushes the plasma membrane against the cell wall of plant, bacteria, and fungi cells as well as those protist cells which have cell walls.
