Cell Transport Quiz

What is the main difference between passive and active transport?

• Passive transport requires energy, while active transport does not.

• Passive transport moves substances from high to low concentration without energy, while active transport requires energy to move substances from low to high concentration.

• Active transport moves substances from high to low concentration, while passive transport does the opposite.

• Both passive and active transport require energy to move substances.

Which of the following is an example of passive transport?

• Phagocytosis

• Exocytosis

• Diffusion

• Endocytosis

What role does a protein play in facilitated diffusion?

• It provides energy for the process.

• It acts as a barrier to prevent diffusion.

• It helps move particles across the cell membrane.

• It changes the concentration gradient.

In osmosis, water moves from an area of:

• High salt concentration to low salt concentration.

• High water concentration to low water concentration.

• Low water concentration to high water concentration.

• Equal water concentration to equal water concentration.

What is required for active transport to occur?

• A helper protein

• Energy in the form of ATP

• A concentration gradient

• Equal concentrations on both sides

During osmosis, if a cell is placed in a solution with a higher salt concentration, what happens to the cell?

• The cell will swell.

• The cell will burst.

• The cell will shrink.

• The cell will remain the same size.

In a YouTube experiment, if side A has a higher concentration of salt than side B, what will happen to the water levels?

• Water will move from side B to side A, raising the water level on side A.

• Salt will move from side A to side B.

• Water will move from side A to side B, raising the water level on side B.

• Water levels will remain unchanged.

What happens to a freshwater plant when placed in saltwater due to osmosis?

• The plant cells will remain unchanged.

• The plant cells will lose water and shrivel.

• The plant cells will burst.

• The plant cells will swell.

If a cell has 10% salt and the environment has 5% salt, what will happen during osmosis?

• Water will move into the cell, causing it to swell.

• Water will move out of the cell, causing it to shrink.

• Salt will move into the cell.

• Salt will move out of the cell.

In a scenario where a cell and its environment both have 10% salt, what will occur?

• Water will move into the cell only.

• The cell will shrink.

• Water will move out of the cell only.

• Water will move both into and out of the cell, with no change in cell size.
