Hypertonic, Hypotonic & Isotonic

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solute compared to the inside of a cell, resulting in no net movement of water.

Front

What happens to a cell in a hypotonic solution?

Back

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

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solute compared to the inside of a cell, leading to water moving out of the cell.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solute than the inside of a cell, resulting in water moving into the cell.

Front

What is the effect of a hypertonic solution on plant cells?

Back

In a hypertonic solution, plant cells lose water, causing them to become plasmolyzed and wilt.

Front

What is the primary movement of water in a hypotonic solution?

Back

Water moves into the cell.

Front

What is the primary movement of water in a hypertonic solution?

Back

Water moves out of the cell.

Front

How does an isotonic solution affect cell size?

Back

An isotonic solution maintains cell size as there is no net movement of water.

Front

What is osmotic pressure?

Back

Osmotic pressure is the pressure required to prevent the flow of water across a semipermeable membrane due to osmosis.

Front

What is the role of osmosis in cells?

Back

Osmosis regulates the movement of water in and out of cells, maintaining homeostasis.
