Hi, would anyone be able to give me some help on my biology essay? I have to write 650 words on “ The process of diffusion and its importance in living organisms.”

 

I honestly don’t know where to even start. I’ve described diffusion and then gone on to narrate what happens when an organism has to breathe.

I’m doing my A-levels. But I am seriously scraping an E. If it’s possible, would anyone be able to give me a laments version on diffusion?

I don’t even know what guidelines I should be following, and what other points I should be branching out on? I’ve looked for information on the internet, on wikipedia and other sites. But everything is just a repeat of itself – or maybe I’m not looking hard enough?

Thankyou for your time.. and please, help!

If you're in highschool anything that you can throw together using this (http://en.wikipedia.org/wiki/Diffusion) should work.

You could base a part on the problems of SA growing slower than volume and then diffusion is not efficient to show why cells are the size they are. I found this interesting.

It may not be related though.
