Cell Membranes (Diffusion and Osmosis)

Cell Membranes (Diffusion and Osmosis)

Multiple Choice

The tendency of an organism to maintain a balanced state in order to stay healthy.

• Stimuli
• Response
• Tropism
• Homestasis

Multiple Choice

The group of organisms that use the process of homeostasis includes

• mammals, only

• animals, only

• plants and animals

• all living things

Multiple Choice

The maintenance of an organism’s internal environment is called:

• compensating
• homeostasis
• balancing
• routine

Multiple Choice

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Multiple Choice

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Multiple Choice

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Multiple Choice

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

Multiple Choice

Osmosis is the movement of ________ across a semi-permeable membrane.

• food

• energy (ATP)

• oxygen

• water

Multiple Choice

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane. 

Multiple Choice

What kind of transport does not require energy?

• Active 
• Vacuole 
• Passive 
• Na/K Pump 

Multiple Choice
