Cell Transport and Energy Flow

The function of the plasma membrane is....

• to regulate what enters and leaves the cell.
• fight bacteria and viruses that enter the cell.
• provide rigid support and protection to the cell.
• make sure each cell can move

What is another term for "selectively permeable"?

• porous
• completely permeable
• permanent
• semipermeable

What type of transport is this?

• Diffusion
• Osmosis
• Facilitated Diffusion
• Active Transport

What type of transport is this?

• Endocytosis
• Facilitated Diffusion
• Active Transport Pump
• Osmosis

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

When the concentration of molecules on both sides of a membrane is the SAME, the solution is

• isotonic
• hypertonic
• hypotonic

If a cell is placed in a hypertonic solution, what will happen?

• Water will move into the cell causing it to swell.
• Water will move out of the cell causing it to shrink.
• nothing.
• Water will move out of the cell causing it to swell.

Which transport does not require energy?

• Passive
• Active
