Osmosis

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of low concentration to an area of high concentration.

Front

True or false: Water always moves from the hypotonic solution to the hypertonic solution.

Back

True.

Front

What does ISO mean in the context of solutions?

Back

ISO means equal.

Front

What happens to an animal cell placed in a hypertonic (salty) solution?

Back

The animal cell will shrink (get smaller).

Front

Where does water move when a cell is in a hypertonic solution?

Back

Water moves out of the cell.

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 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.

Front

What is isotonic solution?

Back

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

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain molecules, like water, to pass through while blocking others.

Front

How does osmosis affect plant cells?

Back

In a hypotonic solution, plant cells swell and become turgid; in a hypertonic solution, they lose water and become plasmolyzed.
