Water molecules move into cell, through a selectively permable membrane, when the surrounding fluid is???

Question

is it

Hypertonic?

Hypotonic?

Isotonic?

supertonic?

Answer 1

hypotonic

Answer 2

Its Hypotonic.If the cell contains more impermeable solute than its surroundings, water will enter it. In the case of animal cells, they will swell until they burst; plant cells do not burst, due to the reinforcement their cell wall provides.

Answer 3

as water molecules are moving into a cell through a selectively permeable membrane, we can say that "osmosis" is taking place.

and osmosis is the movement of water molecules from an area of high concentration to an area of low concentration.

as osmosis is the diffusion of water through a semi-permeable membrane, from a solution of

"low solute concentration" (high water potential) to a solution with "high solute concentration" (low water potential), up a solute concentration gradient,

we can say that

the surrounding fluid is definitely HYPOTONIC.

Hope that helps!!
