Effects of SA; V ration on the rate of diffusion

Postby patrick987 » Sun May 12, 2013 6:32 am

Hello,

Im doing this practical in my year 12 class and my textbook the school supplied does not have the answers to my questions. Pretty Please answer them as these questions need to be done to pass the assignment.

So could you please people answer the questions for me using biological terminology, conventions...? It would be appreciated. At least 1-2 sentences for the following 6 questions.

1. What is diffusion? - I googled this but unsure if it correct
2. What factors can affect diffusion?
3. why do cells require diffusion?
4. How do you think SA: V affects diffusion?
5. Why is size a limiting factor for cells?
6. How is SA; V related to the size of the cube?

and with these 2 questions please detail it more than 2 sentences.

7. The theory of size and rate of diffusion
8. Emphasize how size of cells can affect their exchange of materials.
