What will happen if a cell is kept in a hypertonic solution for a long time?
Cell burst
No change in shape
Swells up
Show plasmolysis
The cell wall is the most rigid component of the cell.
True
False
What will happen if we put an animal cell into a sugar or salt solution?
Cell shrinks
Cell swells
None of these
Cell bursts
If an animal cell is placed into a solution whose concentration of dissolved substances is higher than that inside the cell -
The cell will swell
The solution is described as hypertonic
Both (b) and (c) are correct
The cell will shrivel
If a red blood cell (intracellular concentration of 0.9% salt) was placed into a test tube containing 10% salt solution, what would happen to it?
None of these
The red blood cell would shrink as it loses water to the salt solution in the test tube.
Nothing - the solution is isotonic to the interior of the red blood cell
It would fill with water and burst.
What is plasmolysis?
Contraction of cell protoplast
Expansion of cell protoplast
Cell death
Multiplication of cell
Solutions A and B are separated by a semi-permeable membrane and water moves from A to B. Hence, solution B is
Hypertonic
Isotonic
Hypotonic
None of the above
Why doesn't a plant cell burst when placed in hypotonic condition?
Cell wall withstands the osmotic turgor pressure of the cell
The cell changes the salt concentration of the cytoplasm
The cell drains out excess water
The cell wall does not allow water into the cell
If a cell shrinks when placed in a solution, what will be the tonicity of the solution when compared to cell solution?
Cannot determine
