Cell Transport

Front

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

Back

The animal cell will shrink due to the loss of water.

Front

Define a hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, leading to water moving out of the cell.

Front

What is the process called when molecules move against a concentration gradient?

Back

Active transport.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane.

Front

Define a hypotonic solution.

Back

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

Front

What is the primary function of active transport in cells?

Back

To move molecules from an area of lower concentration to an area of higher concentration, against the concentration gradient.

Front

How does osmosis differ from diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules.

Front

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

Back

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

Front

What role do cell membranes play in transport processes?

Back

Cell membranes regulate the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules pass through the cell membrane via specific transport proteins, without the use of energy.
