What happens to water movement when a solution is isotonic to the inside of a cell?

Back

Water will diffuse back and forth to and from the cell.

Front

Where is there a high concentration of water in a typical biological scenario?

Back

In the vase.

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

What type of transport is osmosis an example of?

Back

Osmosis is an example of passive transport.

Front

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

Back

The cell will shrink.

Front

Define isotonic solution in relation to cells.

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

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 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

Explain the process of diffusion.

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What role do cell membranes play in osmosis and diffusion?

Back

Cell membranes are selectively permeable, allowing certain substances to pass while blocking others.
