osmosis

Front

What happens to red blood cells when they are placed in a hypotonic solution?

Back

The cells will swell and may burst due to the influx of water.

Front

What is the process called when water moves into cells, causing them to become firm?

Back

Osmosis.

Front

What structure regulates the movement of substances in and out of a cell?

Back

Cell Membrane.

Front

In a solution, where is the concentration of dye typically lowest?

Back

At the bottom of the cup.

Front

What direction does water move when a cell is placed in a hypertonic solution?

Back

Out of the cell.

Front

Define osmosis in biological terms.

Back

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

Front

What is a hypotonic solution?

Back

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

Front

What is a hypertonic solution?

Back

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

Front

What effect does osmosis have on plant cells when placed in a hypotonic solution?

Back

Plant cells become turgid and firm due to water entering the cells.

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass while controlling the movement of solutes.
