osmosis

What is osmosis?

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

Why is osmosis important for cells?

Osmosis is critical for maintaining cellular turgor pressure, regulating fluid balance, and transporting nutrients and waste products.

What is the role of a selectively permeable membrane in osmosis?

A selectively permeable membrane allows certain molecules, such as water, to pass through while restricting the movement of solutes.

What happens to a cell in a hypertonic solution?

In a hypertonic solution, water moves out of the cell, leading to cell shrinkage or crenation.
