3
Q
What is diffusion?
A
The movement of particles to fill the space that they’re in
4
Q
Why does diffusion happen quickly in gases?
A
Because gas particles move quickly
5
Q
Why do some cells use diffusion?
A
To get important particles in and out of them
6
Q
Why is diffusion particularly useful?
A
Doesn’t use energy
7
Q
What is osmosis?
A
The movement of water particles down a concentration gradient
8
Q
How does osmosis affect tissues of organisms?
A
Can cause them to lose or gain water
9
Q
If an organism gains water, what happens to the mass?
A
Gains weight/mass
10
Q
