Hypertonic, Hypotonic & Isotonic

Front

What happens to a cell placed in a hypotonic solution?

Back

Water moves into the cell, causing it to swell.

Front

Define a hypotonic solution.

Back

A solution with a lower concentration of solute compared to the inside of the cell.

Front

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

Back

It allows water to enter the plant cell, causing turgor pressure.

Front

What is an isotonic solution?

Back

A solution with an equal concentration of solute compared to the inside of the cell.

Front

What happens to a cell in an isotonic solution?

Back

There is no net movement of water; the cell remains the same size.

Front

Define a hypertonic solution.

Back

A solution with a higher concentration of solute compared to the inside of the cell.

Front

What happens to a cell placed in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

How does osmosis relate to hypotonic, hypertonic, and isotonic solutions?

Back

Osmosis is the movement of water across a semipermeable membrane, influenced by solute concentrations.

Front

What is turgor pressure and how is it affected by hypotonic solutions?

Back

Turgor pressure is the pressure of the cell contents against the cell wall, increased by water entering the cell in a hypotonic solution.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass while controlling solute movement.
