Osmosis is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

A selectively permeable membrane is a barrier that allows certain substances, like water, to pass through while blocking others.

Osmosis is crucial for cells to maintain internal balance and ensure proper physiological function.

A hypertonic solution has a higher solute concentration and a lower water concentration compared to the cell.

When a cell is placed in a hypertonic solution, water moves out of the cell, causing it to shrink.

A hypotonic solution has a lower solute concentration and a higher water concentration compared to the cell.

In a hypotonic solution, water moves into the cell, causing it to swell.

An isotonic solution has an equal concentration of solutes and water as the cell.

When a cell is in an isotonic solution, water moves in and out at equal rates, maintaining the cell's normal size and shape.

In plant cells, a hypotonic solution leads to turgor pressure, making the cell turgid and keeping the plant firm.

A hypertonic solution causes plasmolysis in plant cells, where the cell membrane pulls away from the cell wall, leading to wilting.

A hypotonic solution can cause animal cells to burst due to excessive water intake.

A hypertonic solution causes animal cells to shrink as water leaves the cell.

An isotonic solution is essential for maintaining the normal state and safety of animal cells.

Osmosis plays a vital role in how plant roots absorb water from the soil.

The process of osmosis is fundamental for regulating water balance within animal cells.

Osmosis is involved in processes like pickling or drying foods, such as raisins, by affecting water content.

Water always moves from an area where it is more concentrated to an area where it is less concentrated during osmosis.
