Cell transport Practice

Multiple Choice

The wilted celery can be best explained by...

• Vacuoles do not have enough water

• Vacuoles are filled with too much water

Multiple Choice

Plant cell taking in water when the vacuole is empty is an example of

• homeostasis

• respiration

• tonicity

• photosynthesis

​Other examples of homeostasis...

Multiple Choice

In the drawing, the red molecules can enter the membrane but not the blue molecules. What explains this?

• The membrane is selectively permeable

• diffusion

• equilibrium

• passive transport

Multiple Choice

Which category of cell transport needs no energy and moves from high to low concentration?

• Passive transport

• Active transport

Multiple Choice

What can happen if a cell cannot maintain homeostasis

• the cell will live an thrive

• The cell will likely die

• The cell will increase in productivity

Multiple Choice

Which direction will the water molecules flow if there is no energy added?

Multiple Choice

Will this cell: shrink, swell or stay at equilibrium?

• This cell will swell

• This cell will shrink

• This cell is at equilibrium

​How did you do?

​As water rushes from high to low , then the cell will swell

Multiple Choice

Which direction with the water molecules flow if no energy is added?

Multiple Choice

Will this cell: shrink, swell or stay at equilibrium?

• This cell will swell

• This cell will shrink

• This cell is at equilibrium

Multiple Choice

Which direction will the water molecules move?

• The water molecules have reached equilibrium.

Multiple Choice

What is the difference between osmosis and diffusion?

• osmosis is the diffusion of water across a membrane

• osmosis is the opposite of diffusion

• osmosis and diffusion are the same

Multiple Choice

What type of transport is shown?

• active transport, ATP needed and moves from low to high concentration

• Passive transport-no atp needed

• Active transport- no atp needed, moves from high to low concentration
