All of the following are characteristics of osmosis except
A. passive transport
B. occurs with water
C. solvent will spontaneously move from a hypertonic environment to a hypotonic environment
D. solvent spontaneously moves from an area of high solvent concentration to low solvent concentration
E. is a special form of diffusion.

answer is C.


I thought osmosis is movement of Solvent(water) from hypotonic to hypertonic. Choice D is saying that solute is moving so shouldn't it be false too?

by the way, isn't choice D facilitated diffusion? and choice C active transport?

From Dictionary.com:

osmosis = movement of a solvent through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane
 
Joon, simply, they wrote it backwards. Water (the solvent) is supposed to go FROM the region of low solute concentration TO the region of high solute concentration. This should make sense.

Hypertonic= low water
hypotonic=high water

so its supposed to go from hypo to hyper. just remember, high to low

OH yeah, lol.
I was confused between solvent and solute due to lack sleep.
