Cell Transport Practice

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 leave 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 enter the cell.

Front

What is an isotonic solution?

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 happens to a cell in a hypertonic solution?

Back

Water will leave the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

Water will enter the cell, causing it to swell and potentially burst.

Front

What happens to a cell in an isotonic solution?

Back

There is no net movement of water; the cell remains the same size.

Front

Define osmosis.

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 the role of the cell membrane in transport?

Back

The cell membrane regulates what enters and leaves the cell, maintaining homeostasis.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.
