The dispersal of ink in a beaker of water or perfume molecules moving from one side of the room to another would best show…

• Diffusion

• Osmosis

• Active Transport

• Endocytosis

Osmosis is a type of:

• Active transport

• Passive transport

• Facilitated diffusion

• Endocytosis

When particles such as sugar molecules move OUT of a cell through facilitated diffusion, the cell:

• Gains energy

• Uses energy

• First gains, then uses energy

• Does not use energy

Proteins involved in facilitated diffusion are called:

• Carrier proteins

• Receptor proteins

• Ion proteins

• Diffusion proteins

A student notices that the lettuce in a salad wilts soon after salt is added. Wilting most likely occurs because the lettuce cells:

• Swell when exposed to salt because they take in water through osmosis

• Absorb the extra salt through the plant cell wall

• Release water in the presence of salt because of osmosis

• Lose oxygen when in contact with salt through a plant cell wall

Which of the following DOESN’T require energy?

• Diffusion

• Endocytosis

• Active transport

• Sodium-Potassium Pump

Ridding the cell of materials by moving the materials in vesicles is called:

• Osmosis

• Diffusion

• Exocytosis

• Endocytosis

The plasma (cell) membrane contains channels and pumps that help move materials from one side to another. What are these channels and pumps made of?

• Carbohydrates

• Lipids

• Bilipids

• Proteins

A substance that moves across a cell membrane without using the cell’s energy tends to move

• Away from the area of equilibrium

• Away from the area where it is less concentrated

• Away from the area where it is more concentrated

• Toward the area where it is more concentrated
