Question 3
Question
If an animal cell was placed in a more concentrated solution, what happens?
Answer
-
The cell will shrivel, and possibly die due to loss of water due to osmosis.
-
The cell will expand, and possibly die to the gaining of water due to osmosis.
-
The cell will shrivel, and possible die due to the gaining of water due to osmosis.

Hydrolysis
Question 11
Question
If a plant cell is placed in a more concentration solution that its cytoplasm, what happens?
Answer
-
Water moves out of the cell due to osmosis.
-
Water moves into the cell due to osmosis.
-
The vacuole and cytoplasm shrivel and the cell membrane becomes detached from the cell wall.
-
The cell becomes flacid, loses turgor pressure.

-
the pressure which needs to be applied to a solution to prevent the inward flow of water across a semi-permeable membrane
-
the pressure which needs to be applied to a solution to prevent the outward flow of water across a semi-permeable membrane
