Front

What is a Hypotonic Solution?

Back

A solution that has a lower concentration of solutes and a higher concentration of pure water compared to the inside of a cell, causing water to move into the cell.

Front

What happens to a cell in a Hypertonic Solution?

Back

The cell shrinks as water moves out of the cell due to the higher concentration of solutes in the surrounding solution.

Front

Define Isotonic Solution.

Back

A solution that has the same concentration of solutes as the inside of a cell, resulting in no net movement of water.

Front

What occurs when a cell is placed in a Hypotonic Solution?

Back

The cell swells and may burst as water enters the cell.

Front

What is the effect of a Hypertonic environment on plant cells?

Back

Plant cells become plasmolyzed, losing water and causing the cell membrane to pull away from the cell wall.

Front

Explain the process of Osmosis.

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the significance of the Cell Membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

Describe the term 'Turgor Pressure'.

Back

The pressure exerted by the fluid inside the central vacuole of a plant cell against the cell wall, helping maintain the cell's shape.

Front

What happens to animal cells in an Isotonic Solution?

Back

Animal cells maintain their normal shape and function as there is no net movement of water.

Front

What is the outcome of placing celery sticks in salt water?

Back

The celery sticks are in a hypertonic solution, causing them to lose water and become limp.
