Passive transport

Passive transport

Multiple Choice

The thin, semi-permeable membrane that encloses a cell allows nutrients to enter and wastes to be ____________________.

• digested

• recycled

• protected

• removed

Multiple Choice

When the number of water molecules outside of the cell is greater than inside the cell, which will most likely occur?

• Molecules of water will NOT MOVE either way.

• Molecules of water will move OUT of the cell.

• Molecules of water will move INTO the cell.

• Molecules of water will EVAPORATE.

Multiple Choice

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.
• Into the cell, so the cell swells.

Multiple Choice

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Multiple Choice

Equilibrium?

• a large  amount of substance on  side of the cell and a small amount on the other side
• a small  amount of substance on  side of the cell and a large amount on the otherside
• equal amount of substance on either side of the membrane  
• no particles on either side of the a cell membrane

Multiple Choice

Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
• the diffusion of particles from an area of high concentration to an area of low concentration
• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
• the diffusion of particles from an area of low concentration to an area of high concentration

Multiple Choice
