Which of the following explains a scenario in which energy is required to move across the cell membrane?

• Molecules are moving from an area of high concentration to an area of low concentration

• Molecules are going with the flow of the concentration gradient

• Molecules are moving from an area of low concentration to an area of high concentration

• Energy is not required for any type of transport to occur

Active transport __________, whereas passive transport __________ to occur.

• requires energy; does not require energy

• does not require energy; requires energy

• occurs only in plants; occurs only in animals

• is a type of diffusion; is a type of osmosis

Hypothesize what will occur in the beaker below:

• Water will move to the outside of the bag

• Water will move inside of the bag

• Sucrose will move to the outside of the bag

• Sucrose will move to the inside of the bag

What type of transport is occurring in the image below:

• Facilitated diffusion

• Diffusion

• Osmosis

• Active transport

The diagram shows cellular activity across a cell membrane. Which two processes does this diagram most directly model?

• Energy conversions and synthesis of new molecules.

• Synthesis of new molecules and homeostasis

• Transport of molecule and energy conversions

• Homeostasis and transport of molecules.

A type of cellular transport is shown. Which description best identifies the type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient.

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient.

• Osmosis, because energy is not being used to move molecules with the concentration gradient.

• Endocytosis, because energy is not being used to move molecules against the concentration gradient.

In which type of solution will water move into a cell, causing it to swell?

• Isotonic

• Hypertonic

• Hypotonic

• Neutral

What is the main difference between passive and active transport?

• Passive transport requires energy, while active transport does not

• Active transport requires energy, while passive transport does not

• Passive transport moves molecules against the concentration gradient, while active transport moves molecules with the concentration gradient

• There is no difference

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environment. What conditions cause the contractile vacuole to fill with water?

• The concentration of water is greater outside the cell than inside the cell.

• The temperature of water in the vacuole is higher than the temperature of its environment.

• The concentration of water inside the cell is the same as the concentration outside the cell.

• The temperature of water in the vacuole is lower than the temperature of its environment.
