1

What are the types of passive transport?

Diffusion
Osmosis
Facilitated diffusion

2

What are the types of active transport?

Endocytosis
Exocytosis

3

Water nutrients and __________ need to get into our cells

Oxygen

4

Carbon dioxide and _______ need to get out

Wastes

5

Concentration gradient

The difference in concentration of molecules across a space

6

Molarity

Measure of solute concentration

7

Direction of movement

High --------> low

8

Passive transport

Transport across the cell membrane that does not require energy

9

Moves concentration gradient ________.

Down

10

Diffusion

The movement of molecules from areas of higher concentration (solute) to areas of lower concentration (solute)

11

(Diffusion)
The way ________ and ________ get in/out of cells

Oxygen and carbon

12

Equilibrium

When the commentary ok or a substance is the same throughout the space.
(Ex food coloring)

13

Brownian movement

The random drifting of particles suspended in a fluid ( a liquid or a gas )

14

Osmosis

The process by which water diffuses across the cell membrane from an area of lower solute concentration to an area of higher solute concentration

15

Osmosis

Movement from HIGH ---> LOW water concentration

16

(Osmosis)
Low solute equals ____

High water

17

(Osmosis)high solute equals _____

Low water

18

Turgor pressure

Pressure that water molecules exert against cell walls

19

Plasmolysis

Loss of turgid pressure.
Cells shrink
( wilted plants )

20

Cytolysis

Cells burst because of excess turgor pressure.
Cells swell

21

Hypotonic

When the concentration of solute molecules outside the cell is lower than inside the cell

22

Hypotonic

More water than what is being dissolved

23

Hypertonic

Concentration of solute molecules is higher than water molecules

24

Hypertonic

More solute equals less water

25

Water travels to ___

Hypertonic

26

Isotonic

Concentrations are equal.
Water will diffuse into and out of the cell at equal rate.

27

Egyptian mummification

-drying out process
-40 days to dry out
-salt put on top
-hypo to hyper
-dried fruit

28

Facilitated diffusion

Movement of molecules that cannot diffuse rapidly without the assistance of carrier protein.

29

Active transport

Transport across the cellular membrane that requires energy.
Goes against concentration gradient.
