Cell Transport Exit Ticket

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.

Cell membranes are described as selectively permeable.

Four students were asked to explain what this means. Which one is correct?

• Student 1: Cell membranes prevent all materials from entering the cell.

• Student 2: Cell membranes only provide structural support for the cell.

• Student 3: Cell membranes regulate which substances can enter and exit the cell.

• Student 4: Cell membranes allow water and water-soluble substances to enter the cell.

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

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

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

Passive Transport means

• Energy is used

• No energy is used

• Energy is created

Permeable means

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

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

• Osmosis
• Diffusion
• Equilibrium
