LIFE SCIENCE

Detailed explanation-1: -The added salt makes the solution hypotonic compared to the cell. Water will enter the cell by osmosis. Water would leave the cell by osmosis, causing the volume of the cytoplasm to decrease.

Detailed explanation-2: -6. When plant cells are put in really salty water, water diffuses/moves out of the cell and the central vacuole shrinks. When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up.

Detailed explanation-3: -A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.

Detailed explanation-4: -The salt solution being hypertonic, the water potential of the salt solution is less than that of the cytoplasm of the cell. Hence water comes out of the cell through osmosis and protoplast shrinks.
