Detailed explanation-1: –A salt-water snail is mistakenly put into a freshwater tank. The salt concentration is higher within the snail than in the tank, so water will travel from the tank into the snail to equal the salt concentration. The snail will swell and may possibly die.

Detailed explanation-2: -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.

Detailed explanation-3: -When we put animal cells into pure, fresh water (H2O), water enters the cells as a result of osmosis, and making the cell expand. This is because osmosis states that water will diffuse down a concentration gradient through the cell’s partially permeable membrane.

Detailed explanation-4: -Water in cells moves toward the highest concentration of salt. If 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.

Detailed explanation-5: -The cell swells up when endosmosis occurs. Endosmosis is when the water molecules move from the outside to the inside of the cell through the cell membrane. For example, the passage of water from root hair cells to cortical cells of the root.
