Diffusion Flashcards
1
Q
What is diffusion?
A
Movement of particles from where there are lot’s of them to where there are fewer of them
2
Q
fancy way of saying it?
A
Diffusion is the movement of particles to a higher concentration to a lower concentration
3
Q
What is the difference in concentration
A
Concentration gradient, the bigger the difference in concentration the faster the rate
4
Q
What will give a higher diffusion rate
A
higher temperature, more energy which means the particles will move around faster
5
Q
What do cell membranes do?
A
Let only small molecules go through and big molecules like starch and protein cannot
