SA/Vol ratio (advantages to microscopic organisms) Flashcards
1
Q
a key advantage of SA/Vol ratio is…
A
fast exchange of gases, nutrients and waste
2
Q
SA/Vol have shorter…
A
diffusion distances
3
Q
what does SA/Vol allow?
A
unicellular organisms to thrive without complex transport systems
4
Q
larger SA/Vol organisms need…
A
specialised structures to compensate for lower SA/Vol ratios
5
Q
What is the formula for SA/Vol ratio?
A
SA = L x W x No. of slides
Vol = L x W x H
