OSMOSIS/DIFFUSION

Front

What is the process called when molecules move from an area of higher concentration to an area of lower concentration?

Back

Diffusion

Front

What term describes a solution that has a higher concentration of solutes compared to the inside of a cell?

Back

Hypertonic solution

Front

What happens to a cell when it is placed in a hypertonic solution?

Back

The cell will shrink as water moves out of it.

Front

What is the term for the movement of water across a selectively permeable membrane?

Back

Osmosis

Front

What type of transport does not require energy to move substances across a cell membrane?

Back

Passive transport

Front

What is the effect on an animal cell placed in a hypotonic solution?

Back

The cell will swell and may burst due to water influx.

Front

What is the term for a solution with the same concentration of solutes as the inside of a cell?

Back

Isotonic solution

Front

What is the primary difference between diffusion and osmosis?

Back

Diffusion refers to the movement of solutes, while osmosis specifically refers to the movement of water.

Front

What happens to an egg placed in pure water for 48 hours?

Back

The egg will gain water and swell due to osmosis.

Front

What is the role of the cell membrane in osmosis and diffusion?

Back

The cell membrane is selectively permeable, allowing certain substances to pass while blocking others.
