Cell Transport

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

True or False: Osmosis is an active process and requires extra energy for it to occur.

Back

False

Front

What happens to a cell in a hypotonic solution?

Back

The cell gains water and swells.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the process called when a cell expels materials?

Back

Exocytosis.

Front

What does a semipermeable membrane do?

Back

A semipermeable membrane allows certain molecules to pass through while blocking others.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell takes in materials by engulfing them in a membrane.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and shrinks.
