How can a cell protect itself from being cytolized?

[hikki_pop]

Osmosis:
a. presence of h20 molecules
b. presence of a semi-permeable membrane
c. direction: from a region of higher concentration to a region of lower concentration


* osmosis is a passive transport, which is defined as the movement of molecules without the expenditure of cellular energy.

1. what factors are important to bring about a faster movement through a membrane?

2. how can a cell protect itself from being cytolized?

you could change the concentration gradients on either side of the membrane, i guess, and well.. plant cells protect themselves pretty well with the cell walls... they just bulge. i believe so, anyways. don't remember exactly.
