Surface area to volume ratio Flashcards
1
Q
Do small organisms have a large SA:V ratio or a small SA:V ratio?
A
Large SA:V ratio
2
Q
Do large organisms have a large SA:V ratio or a small SA:V ratio?
A
Small SA:V ratio
3
Q
Why do larger organisms have adaptations of their exchange surfaces?
A
Diffusion of substances will be slow in large organisms due to small SA:V ratio
These organisms will have adaptations to make exchange more efficient
