Diffusion Flashcards
1
Q
Defintion
A
Movement of particles from an area of higher concentration to an area of lower concentration
2
Q
Example of diffusion
A
Oxygen moves from the blood into the cell by diffusion from higher to lower concentration
3
Q
Factors affecting rate of diffusion
A
Concentration gradient
Surface area to volume ratio
Distance
Temperature
4
Q
Concentration gradient
A
Steeper the concentration gradient the faster the diffusion rate
5
Q
Surface area to volume ratio
A
Larger surface area to volume ratio, the faster the rate of diffusion
6
Q
Distance
A
The smaller the distance, the faster the diffusion rate
7
Q
Temperature
A
The higher the temperature, the faster the diffusion rate
