THE PLASMA MEMBRANE ok basicly what the membrane does is it separtes the cells contents from its environment. ... the palsma membrane is selectivly permeable so its ‘picky’ an example of this would be a tea bag. ... well the phospholipid bilayer is made up of two things :phosphate and fatty acid the phosphate is polar meaning it can disolve in water and it is hydrophilic which means it is H2O loving the lipid (fatty acid) is non polar which means is will not dissolve in water it is hydrophorbic so it is H2O fearing a way of remembering that is looking at phorbic like phobia it means fear <---- head (phosphate)(polar) <----tail (lipid (fatty acid)) (non polar) clolesterol are embedded in the bilayer to (1) restrict movement of phoshorids and (2) make the membrane strong and flexible OOOOOXOOOOOXOOOO in this pic. |
