effect of osmosis on cells....​

Answer 1

Effects of osmosis on cells

• Red blood cells placed in a solution with the same water concentration as their cytoplasm (0.85 per cent salt solution) will not experience an overall change in volume.
• No osmosis occurs.
• Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up and burst.
• Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
• Red blood cells placed in a solution with a lower water concentration compared to their contents (eg 1.7 per cent salt solution) will lose water by osmosis and shrink.
• Water will diffuse from a higher water concentration inside the cell to a lower water concentration outside the cell.

Answer 2

Step-by-step explanation:

Effect of Osmosis on Cells

Osmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.

An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.

The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure.
