Mastering Cell Transport

What is the process called where molecules spread from an area of high concentration to an area of low concentration?

• Osmosis

• Active transport

• Diffusion

• Endocytosis

Which of the following does NOT require energy from the cell?

• Active transport

• Passive transport

• Endocytosis

• Exocytosis

What is the term for the movement of WATER across a selectively permeable membrane?

• Diffusion

• Osmosis

• Filtration

• Active transport

Which of the following is an example of active transport?

• Facilitated diffusion

• Protein pump

• Simple diffusion

• Osmosis

What is the main difference between passive transport and active transport?

• Passive transport moves ions from low to high concentration, while active transport moves them from high to low concentration.

• Active transport requires cellular energy, while passive transport does not.

• Passive transport can only move water, while active transport can move any substance.

• Active transport can only occur in animal cells, while passive transport can occur in all cells.

During which process do cells take in large particles by engulfing them?

• Exocytosis

• Osmosis

• Endocytosis

• Diffusion

What is the process called when a cell releases large amounts of material from its interior to the exterior?

• Osmosis

• Active transport

• Endocytosis

• Exocytosis

Which of the following statements is true about diffusion?

• It occurs only in liquids.

• It requires energy from ATP.

• It can occur in gases, liquids, and solids.

• It is a form of active transport.

A cell is typically 97% water and 3% dissolved salts. Grace was conducting a science experiment in which she placed a cell in a solution with a lower concentration of water (94% Water and 6% salt). Knowing that WATER moves from an area of high concentration to low concentration, predict what will happen to the size of the cell?

• The cell swelled because water moved into the cell.

• The cell stayed the same size because the concentration of solutes was balanced.

• The cell shrunk because water moved out of the cell.

• The cell divided because of the excess water.

Which of the following is NOT a characteristic of passive transport?

• It moves substances down their concentration gradient.

• It includes processes such as osmosis and diffusion.

• It requires special protein channels or carriers.

• It uses energy in the form of ATP.
