Understanding Passive Transport and Osmosis

Which of the following is a type of passive transport?

• Active transport

• Facilitated diffusion

• Endocytosis

• Exocytosis

What is the primary difference between osmosis and diffusion?

• Osmosis involves the movement of solutes, while diffusion involves the movement of water.

• Osmosis requires energy, while diffusion does not.

• Osmosis involves the movement of water across a semipermeable membrane, while diffusion involves the movement of solutes.

• Osmosis occurs only in plants, while diffusion occurs in animals.

Which of the following best describes osmosis in cells?

• The movement of water from an area of low solute concentration to an area of high solute concentration.

• The movement of solutes from an area of high concentration to an area of low concentration.

• The movement of water from an area of high solute concentration to an area of low solute concentration.

• The movement of solutes across a semipermeable membrane using energy.

How does passive transport contribute to homeostasis in cells?

• By using energy to move substances against their concentration gradient.

• By allowing cells to maintain a stable internal environment without using energy.

• By actively transporting nutrients into the cell.

• By preventing the movement of substances across the cell membrane.

What role does osmosis play in maintaining homeostasis in plant cells?

• It helps in the active transport of nutrients.

• It regulates the water balance by controlling the movement of water into and out of the cell.

• It prevents the entry of harmful substances.

• It facilitates the movement of proteins across the cell membrane.

How does facilitated diffusion differ from simple diffusion?

• Facilitated diffusion requires energy, while simple diffusion does not.

• Facilitated diffusion involves the use of transport proteins, while simple diffusion does not.

• Facilitated diffusion moves substances against their concentration gradient, while simple diffusion does not.

• Facilitated diffusion occurs only in plant cells, while simple diffusion occurs in all cells.
