Discussion of all aspects of cellular structure, physiology and communication.
i'd say so. if the temp is higher, then probably it would increase the rate of diffusion by increasing the kinetic activity of the solution: the molecules within the solution would be moving about more vigorously and so naturally the chances of them moving through pores in a membrane would be much better. also everyone knows that when things heat up they expand. i guess this would be the case for a cell membrane. like a circle on the surface of a balloon. when you blow it up the circle expands. same goes for a pore in a cell membrane i guess. this seems intuitively correct, but if i'm wrong someone let me know.

first of all, diffusion does not occur when a cell is placed in a hypertonic solution, only osmosis will occur.
Temperature will only affect the rate of diffusion due to the fast moving of the particles.
Rate of osmosis depends on the water potential in a particular solution or cell.
No, it's not. Google and you will see why.

No they are not. Simple diffusion is the passing of small or/and hidrophobic molecules from one side of the plasma membrane to the other(from higher concentration to lower concentration). The process is influenced by heat and takes place in the lipid bilayer.
Osmosis is a different process, that consists on water moving from a more diluted solution towards a more concentrated one. The process is less influenced by heat because, although a bit of water can pass through the bilayer, the biggest quantity of water is moved by aquaporins. For their descovery, the Nobel prize was given in 2002.
Does that answer your question?
