Understanding Osmosis and Diffusion

What is osmosis?

• Osmosis is the process of energy production in cells.

• Osmosis refers to the movement of nutrients into cells.

• Osmosis is the diffusion of gases across a membrane.

• Osmosis is the movement of water across a membrane due to concentration differences.

How does diffusion differ from osmosis?

• Diffusion is the movement of any particles, while osmosis specifically refers to the movement of water.

• Diffusion only occurs in gases, while osmosis occurs in liquids.

• Osmosis is the movement of any particles, while diffusion is only for water.

• Diffusion requires energy input, whereas osmosis does not.

What is the role of a semipermeable membrane in osmosis?

• It allows the passage of solutes while restricting water movement.

• The role of a semipermeable membrane in osmosis is to allow the passage of water while restricting solute movement.

• It facilitates the movement of both water and solutes equally.

• It prevents any movement of substances across the membrane.

What factors affect the rate of diffusion?

• Shape of the container

• Humidity levels

• Temperature, concentration gradient, particle size, and medium of diffusion.

• Color of the particles

What is the concentration gradient in the context of diffusion?

• The concentration gradient is the temperature difference affecting diffusion.

• The concentration gradient is the speed at which a substance moves.

• The concentration gradient is the difference in concentration of a substance across a space.

• The concentration gradient is the total amount of a substance in a space.

What happens to a cell in a hypertonic solution?

• The cell remains unchanged in size.

• The cell swells due to excess water intake.

• The cell divides into two smaller cells.

• The cell shrinks due to water loss.

What is meant by isotonic solutions?

• Isotonic solutions have a higher solute concentration than another solution.

• Isotonic solutions are always solid at room temperature.

• Isotonic solutions contain no solute at all.

• Isotonic solutions are solutions with equal solute concentration compared to another solution.

How do plant cells react to hypotonic solutions?

• Plant cells remain unchanged in hypotonic solutions.

• Plant cells swell and become turgid in hypotonic solutions.

• Plant cells shrink and become plasmolyzed in hypotonic solutions.

• Plant cells die immediately in hypotonic solutions.

Can osmosis occur without a membrane?

• No, osmosis cannot occur without a membrane.

• Yes, osmosis can occur without a membrane.

• Osmosis only requires a semi-permeable membrane.

• Osmosis can happen in a vacuum without any barriers.

What is the significance of osmosis in living organisms?

• Osmosis is a process that occurs only in animals.

• Osmosis prevents all forms of cellular waste.

• Osmosis is significant for maintaining cell turgor, regulating internal environments, and facilitating nutrient absorption and waste removal.

• Osmosis is only important for plant growth.
