- investigating the osmotic values of chinese radish and potato cores osmosis is the movement of water from an area of high water potential (î¨) to an area of low water potential through a selectively permeable membrane. in theory, no osmosis should occur, so the percentage mass change should be at zero (crosses x-axis).♦ leave it for a longer amount of time (for example three hours,Instead of half an hour) ♦ use bigger potato blocks (hence use a bigger of that weird tool) ♦ we decided to keep the same range of concentrations ♦ use a pipette to make accurate measurements ♦ measure mass up to two decimals ♦ next time to have 20 test tubes, to repeat the experiment twice so we can obtain reliable results in real experiment:Year 11 biology coursework. the change in length and width (when cut into cylindrical shape as previously) of the potato cell can tell us if osmosis did occur, and including its effects on the cell. introduction this is a real a-level school project and as such is intended for educational or research purposes only. this is where water passes into the vacuole by osmosis since the water molecules in the solution is attracted to the other water molecules in the cell, this is known as net endosmosis occurring and the cell becomes turgid.- biology enzymes coursework prediction: i think that the enzyme will work best at 45.

this will tell us how osmosis works through different concentrations. this experiment we are going to be studying the affects of osmosis. how my experiment was suitable: ♦ i think the time i left it for was reasonable enough ♦ i am pleased with my concentration range, i reckon it was suitable and with enough points to make a good graph with a smooth curve or a straight line ♦ finding out the mass before the potato cells were put into the solution and then comparing it with mass after osmosis had taken place was a good way of showing how osmosis works and how it affected the plant cells’ shape and structure improvements of the experiment ♦ repeat it for a third time ♦ use one potato only- and a larger one so you have enough to cut out 2o equal potatoes ♦ use biurettes or syringes (better equipment) to make more accurate measurements ♦ despite the fact that i am happy with the amount of time i left the potato cells for osmosis to occur, it would not do any harm if i increased it to an extra hour, as maybe more time can further work if i were to do any further work on this investigation that would support my prediction, then i would test the factor of length and maybe width as well.- physical anthropology “is in large part, human biology seen from an evolutionary perspective” (jurmaln, kilgore & trevathan, 2011).- human development shaped by biology and experience the first core concept suggested by from neurons to neighborhoods depicts human development forming from the interplay of an individual’s biology and experience. (the year 11 biology coursework further apart they are the less accurate results you get). so using another potato, we skinned the skin (since the skin is like a barrier and so getting rid of it would allow the process of osmosis to occur more efficiently) and placing them in chronologic order on a tile, we weighed each one.
