Form-fits-function theme?

Question

I have a question on my biology homework that says form-fits-function theme.

Do you know what that means?

Please and Thank you.

Answer 1

i think you ask a great question.

i can think of a perfect example for you.

the red blood cell...

it has a cellular form that can maneuver throughout the smallest parts our our body, and still function very well.

it is an unusual cell, in the sense that it has no nucleus.  

however, this allows it to perform its function, which is to oxygenate the body. even in the tightest notches or the body.  

flex your biceps.  

you can squeeze them as tight tight as you want, yet red blood cells will still find a way inside of them.

of course, when you relax your biceps, more red blood cells will flood in, as the form of the muscle regains a relaxed form.

here is something to think about...

only red blood cells can enter and leave the brain (according to "classical" science).  

there is something about the form of the brain that will only allow red blood cells to enter and exit.

all other cells are denied access into the brain.

scientists call this the "blood-brain barrier".

it is a mystery why red blood cells are given special privilege to enter the brain, while other whole blood cells are denied access.

maybe red blood cells are formed to function in the brain.  

maybe the brain formed to function with the red blood cells.

what do you think?

best karma to you for asking this great question!
