|
Water will pass from inside the cell to outside by diffusion
|
|
|
Water will enter the cell by osmosis
|
|
|
Salt will escape from the cell through the semipermeable membrane
|
|
|
There will be no movement of substances between the cell and it’s environment
|
Detailed explanation-1: -As there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt. Q. If a cell is placed in solution there will be no net flow of water into or out of the cell.
Detailed explanation-2: -Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution.
Detailed explanation-3: -Final answer: A cell will swell up if the concentration of water molecules in the surrounding medium is higher than water molecules concentration in the cell.
Detailed explanation-4: -A higher concentration is hypertonic for cells. A hypertonic solution has a lower water concentration than the cell cytosol, so water moves out of the cell, causing the cell to shrivel. Diffusion is the net movement of a substance from an area of high concentration to an area of low concentration.
Detailed explanation-5: -When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up. When plant cells are put in fresh water, water diffuses/moves into the cell and fills up the central vacuole.
