Surface area to volume ratio Flashcards
1
Q
how to calculate surface area?
A
(length times height)times number of sides
2
Q
calculate volume equation ?
A
length X height X width
3
Q
do smaller organisms have a large or small surface areas to vol ratio ?
A
large sa to volume
4
Q
how do tiny organisms do gas exchange ?
A
small diffusion pathway =simple diffusion
5
Q
will larger organisms have adaptations to be more efficent ?
A
yes
6
Q
give examples of adaptations ?
A
villi and microvilli
alveoli and bronchoioles
spiricales and tracheoles
gill filaments and lammellae
thin wide leaves
many capillaries
7

A
large surface area
lots of channel and carrier proteins
