Biology homework question?

Question

I have to use an explain of how structure and function correlate in biology.

Anyone have any ideas?

Answer 1

The structure of a ROOT HAIR.

structure: has a large surface    function: larger surface allows more water absorption    

(s) has a large vacuole             ( f)  can accumulate more water

(s) no cuticle                           ( f) cuticle's  presence will slow water absorption    

(s) has thin cell wall                 ( f) thinner layers will allow faster absoption

(s) consentrated cell sap          ( f) helps to maintain osmogradient        

Answer 2

haha first thing that came to my mind is the villi in the small intestine of the digestive system.

the villi are used to absorbe nutrients passing through the small intestine....they are small finger-like-projections that stick out form the intestinal wall...this GREATLY increases the surface area of the intestine so more nutrients and etc.. and can absorbed

consult your text book!

or look at really any system in the human body

this villi example is similar to the aveioli in the lungs (sorry about spelling!) they greatly increase the surface area that gas exchange can occur...so that the O2 can be "traded" for the CO2
