Want this question answered?
If cells are placed in a hypotonic solution the cells gain water. The hypotonic solution has lower solute concentration then the cell's cytoplasm so the water will enter via osmosis.
An isotonic solution is one in which the ionic environment is similar to that of the cytoplasm. Hence, when a cell is placed in an isotonic solution, there is no net diffusion of water into or out of the cell. The cell remains intact.
I believe the solution would be considered hypotonic. in which case the amoeba would let water (H2O) out of its body to regulate the solute concentration (to make it equal)
Suger
When a cell is put in a hypertonic solution, it shrinks and shrivels. You alwasy have t say: This solution is hypertonic to ...A hypertonic solution means that there is more matter in the solution than in the object it is compared to. The cell will shrink and shrivel because the water will leave the cell to try to dissolve the matter outside of it.
Hypotonic
Isotonic solution
isotonic.
Hypotonic :) good luck on plato :D
A raw egg without its shell but with its inner membrane intact will either swell or shrink when placed in a solution because of the concentration gradient. The membrane is semi-permeable. An egg will shrink if it is placed in a solution that has a higher solute concentration than inside it. It will swell if it is placed in a solution that has a lower solute concentration than inside the egg.
The water will move towards the higher solute concentration until both sides are isotonic.
The cytoplasm looses water to the cell exterior.
