Cell Transport

Multiple Choice

What is the main difference between active transport and passive transport in a cell?

• If energy is needed

• The direction molecules move

• Whether the cell has to move or not

• All of these answers are correct

Multiple Choice

Osmosis is an example of active transport.

• True

• False

Multiple Choice

Molecules naturally move from an area of high concentration to low concentration unless something blocks them.

• True

• False

Multiple Choice

If the concentration of a molecule is the same on the inside of a cell as the outside of the cell, the molecule will stop diffusing (moving).

• True

• False

Multiple Choice

Water molecules can move freely in and out of a cell through small pores in the cell membrane.

• True

• False

Multiple Choice

What is the specific name given to the movement of water molecules from an area of higher water concentration to an area of lower water concentration?

• Osmosis

• Aquaporin

• Facilitated Diffusion

• Active Transport

Multiple Choice

What is the general name given to a substance that is dissolved in water?

• solute

• solution

• ion

• aquatic

Multiple Choice

What is the general name used to describe a solution that has the same solute concentration as the inside of a cell?

• hypertonic

• hypotonic

• isotonic

• balanced

Multiple Choice

No water molecules diffuse in and out of a cell if it is placed in an isotonic solution.

• True

• False

Multiple Choice

What is the general name used to describe a solution that has LESS solute concentration than the inside of a cell?

• Isotonic

• Hypertonic

• Hypotonic

• Balanced

Multiple Choice

What happens to the size of a cell if it is placed in a hypotonic solution?

• It will get bigger

• It will get smaller

• It will stay the same size

• The cell will shrivel up and die

Multiple Choice

In the Eggsperiment Lab, which solution was hypertonic compared to the inside of the egg?

• corn syrup

• pure water

• neither were hypertonic

• both were hypertonic

Multiple Choice

Active transport often involves moving molecules from a lower concentration to a higher concentration.

• True

• False

Multiple Choice

What is the name used to describe how a cell moves particles OUT of the cell if they are too large to diffuse through the cell membrane?

• exocytosis

• endocytosis

• phagocytosis

• pinocytosis
