Hi I'm a freshman in college and we have to do a lab report on an experiment we just ran. It was a very simple test on semipermeability. My problem is I am supposed to come up with some works cited to add to the report and I am having a hard time finding information using this particular verbage (semipermeability). Is semipermeable the same as selectively permeable? Can someone lead me to sites or even books that might help with my research on this subject. Any help will be greatly appreciated.
Thanks

THE term in relation with semipermeable membranes is osmosis.

Thank you. I understand osmosis (the moving of water from higher concentrations to lower concentrations). I guess I am even more confussed as to what I am looking for. I guess it's time to go back to the proverbial drawing board and revisit my text book.
Thanks again for your assistance.

semipermeable membrane allows only some substances to go through. There's a limit for substances to enter to the other side through semipermeable membrane..
plant cell membrane is semi permeable.

all cell membranes are semipermeable, not just plant cell membranes.
