Essay- Plasma Membranes

Showing 1 to 4 of 4

I was just wondering if anyone has written/ has a good template of the essay with the title "The strucure and importance of the plasma membranes that are found within and around cells"

I can't seem to find any sort of mark scheme or marking points that might shove me in the right direction? 

Anyone have any good points for it? Feel free to message them to me too.

Thanks

You have to write an essay on this? Ewwww
How many marks and i'm guessing this is for A level?
I would start making a list of all of the membrane bound organelles within a cell - look at their functions and importance withint the cell
Think about the processes that happen in the membrane
Think about the main function of the membrane
You could look at them in plants too
Then look at bacterial cells - prokaryotes that don;t contain membrane bound organelles, think why and how they;re better off this way/ why they aren;t needed

Talk about the structure of it so from unit 1 and  membrane bound organelles. chloroplasts mitochondria, diffusion, osmosis, active transport, ...

then you can talk about respiration in the membrane. 

resting/action potential.

mention prokaryotic cells and how they differ....

errm all i can think of that the moment.. this essay is okay but the next one on bacteria is a killer .. good luck :)
