Unit 4 Review Part 1

Which of the following describes a semipermeable/selectively permeable membrane?

• a membrane that allows everything to pass through

• a membrane that only allows certain molecules to pass through

• a membrane that only allows water to pass though

• there are not different kinds of membranes

During this kind of transport, small molecules are moved across the membrane

• Passive Transport

• Active Transport

• Endocytosis

• Pinocytosis

During this kind of transport, large molecules are moved across the membrane with the aid of transport proteins

• Passive Transport

• Active Transport

• Facilitated Diffusion

• Osmosis

Facilitated Diffusion is a type of...

• Active Transport

• Passive Transport

Which of the following are types of passive transport?

• osmosis

• diffusion

• bulk transport

• facilitated diffusion

Which of the following correctly matches the energy and movement that happens during diffusion?

• uses energy; H to L

• uses energy; L to H

• no energy; H to L

• no energy; L to H

The correct description for hypotonic and hypertonic solutions is below, choose the correct answer.

• Hypo swells; Hyper shrinks

• Hypo shrinks; hyper swells

• Hypo swells; hyper swells

• Hyper shrinks; Hypo shrinks

In hypotonic solutions, the water moves which direction?

• into the cell

• out of the cell

• in and out at the same rate

In hypertonic solutions, the water moves which direction?

• into the cell

• out of the cell

• in and out at the same rate

During facilitated diffusion what type of molecules are capable of getting across the membrane?

• smaller molecules

• bigger molecules

• small molecules with the help of a protein channel

• big molecules with the help of a protein channel
