Understanding Osmosis and Its Concepts

What is osmosis?

• Osmosis is the process of energy transfer between 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 osmotic pressure affect fluid movement?

• Osmotic pressure prevents water from moving between compartments.

• Osmotic pressure drives water movement towards areas of higher solute concentration.

• Osmotic pressure causes solutes to move towards areas of lower concentration.

• Osmotic pressure has no effect on fluid movement.

What type of membrane allows the passage of some substances but not others?

• Selectively permeable membrane

• Impermeable membrane

• Freely permeable membrane

• Non-selective membrane

What is the difference between isotonic and hypertonic solutions?

• Isotonic solutions cause cells to swell, while hypertonic solutions maintain cell shape.

• Hypertonic solutions maintain cell shape, while isotonic solutions cause cells to burst.

• Isotonic solutions have a higher concentration of solutes than hypertonic solutions.

• Isotonic solutions maintain cell shape, while hypertonic solutions cause cells to shrink.

What happens to water movement in isotonic solutions?

• Water moves out of the cell only.

• Water movement increases significantly.

• Water movement stops completely.

• Water movement remains balanced with no net change.

Define passive transport in the context of osmosis.

• Osmosis is the movement of solutes across a membrane from high to low concentration.

• Passive transport in osmosis is the movement of water across a membrane from low to high solute concentration without energy.

• Passive transport in osmosis involves the movement of water from high to low solute concentration.

• Active transport requires energy to move water against the concentration gradient.

How does osmosis occur between interstitial and intracellular compartments?

• Osmosis happens when cells release water into the bloodstream.

• Osmosis is the active transport of ions across a membrane.

• Osmosis occurs by the movement of nutrients from intracellular fluid to interstitial fluid.

• Osmosis occurs by the movement of water from interstitial fluid to intracellular fluid through a semipermeable membrane.

What is the significance of solute concentration in osmosis?

• Solute concentration has no effect on osmosis.

• Solute concentration determines the direction and rate of water movement in osmosis.

• Higher solute concentration always leads to faster osmosis.

• Osmosis only occurs in pure water, regardless of solute concentration.

What occurs when cells are placed in a hypertonic solution?

• Cells lose water and shrink.

• Cells gain water and swell.

• Cells burst and release their contents.

• Cells remain unchanged in size.

Explain the role of water molecules in osmosis.

• Water molecules do not move during osmosis and remain stationary.

• Water molecules move from areas of low solute concentration to areas of high solute concentration during osmosis.

• Water molecules move from areas of high solute concentration to areas of low solute concentration during osmosis.

• Osmosis involves the movement of solute molecules instead of water molecules.
