Hypertonic, Hypotonic, and Isotonic Solutions-Plant Cells

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell and leading to cell shrinkage.

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrivels as water moves out of it.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells and may burst as water moves into it.

Front

What is an isotonic solution?

Back

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

Front

What happens to a cell in an isotonic solution?

Back

The cell remains the same size as water moves in and out equally.

Front

What role does the cell membrane play in maintaining homeostasis?

Back

The cell membrane controls what substances may enter or leave the cell, helping to maintain a stable internal environment.

Front

Do animal cells have cell walls?

Back

No, animal cells do not have cell walls; only plant cells have strong cell walls.

Front

What is osmosis?

Back

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

Front

How does osmosis affect plant cells in a hypotonic solution?

Back

In a hypotonic solution, water enters plant cells, causing them to swell and become turgid, which helps maintain structural integrity.
