Cell Transport

Front

What is passive transport?

Back

Cell membrane transport that occurs without energy.

Front

What is active transport?

Back

Cell membrane transport that requires energy to move substances against their concentration gradient.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink.

Front

What does selectively permeable mean?

Back

It means that certain things can enter while others cannot.

Front

Which of the following is not a type of passive transport: Osmosis, Diffusion, Endocytosis, or Facilitated Diffusion?

Back

Endocytosis.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What is the role of the cell membrane?

Back

To protect the cell and regulate what enters and leaves.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.
