Osmosis

Front

What is osmosis?

Back

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

What happens to an animal cell in a hypertonic solution?

Back

The animal cell will shrink because water moves out of the cell to the area of higher solute concentration.

Front

What happens to an egg placed in pure water for 48 hours?

Back

The egg will gain water and swell due to osmosis.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.

Front

What does isotonic mean?

Back

Isotonic refers to a solution that has the same solute concentration as another solution, resulting in no net movement of water.

Front

What does hypertonic mean?

Back

Hypertonic refers to a solution that has a higher solute concentration compared to another solution.

Front

What does hypotonic mean?

Back

Hypotonic refers to a solution that has a lower solute concentration compared to another solution.

Front

What role does the cell wall play in plant cells?

Back

The cell wall provides protection and structural support to plant cells.

Front

What is the significance of water movement in osmosis?

Back

Water movement in osmosis is crucial for maintaining cell turgor pressure and overall cell function.

Front

How does osmosis affect plant cells in a hypotonic solution?

Back

In a hypotonic solution, plant cells will swell and become turgid as water enters the cell.
