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!

Sorry about the wording. Here it is reworded:

If I fell 100ft into a deep pool, I would hit the floor QUICKER if it was filled with:

a. Plastic balls (like a kid's playroom)

b. Polystyrene balls (in beanbags)

Sorry if I caused any confusion. It's just me and my friend had a disagreement, she thought that falling in polystyrene would get you 'down' quicker, whereas I thought the opposite .

Question: If I fell 100 feet into a large, deep pool, which of the following would take LONGER to touch the bottom of the pool.

1. Plastic balls (like a kid's playroom)

2. Polystyrene balls (in beanbags)

Thanks!
