Cell Transport Vocabulary Review

The movement of water molecules through a cell membrane.

• permeable

• diffusion

• active transport

• osmosis

Movement of molecules from an area of high concentration to an area of low concentration.

• diffusion

• passive transport

• homeostasis

• cell transport

Permeable means

• allowing water through a membrane.

• the cell uses lots of energy to diffuse molecules through a membrane

• allowing liquids and gases to pass through a membrane.

• not using energy to pass materials through a membrane.

Key word for active transport:

• energy

• not using energy

• movement

• balance

A dog panting, a person shivering, a bear hibernating, stomach growls when hungry are all examples of

• active transport

• homeostasis

• diffusion

• permeable

What term refers to the concept that molecules move across a cell membrane?

• osmosis

• diffusion

• homeostasis

• cell transport

What is most likely to happen to a cell if homeostasis is not maintained

• Many cell processes in the cell will slow down or even stop.

• The cell will eliminate waste more efficiently.

• The cell will immediately divide.

• Cell processes will continue unchanged.
