1
Q
What is diffusion ?
A
The spreading of particles moving from an area of higher concentration to an area with lower concentration
2
Q
Why do cells need oxygen ?
A
For respiration which is carried out by mitochondria
3
Q
What affects diffusion ?
A
The difference in concentration
The temperature
Surface area
4
Q
How does the surface area impact diffusion ?
A
The larger the surface area the greater the rate of diffusion
5
Q
How does temperature affect the rate of diffusion ?
A
The higher the temperature the greater the rate of diffusion
6
Q
How does concentration effect the rate of diffusion?
A
The smaller the concentration is the slower diffusion will be
The higher the concentration is the faster diffusion will be
