Osmosis Pt 2

What is osmosis?

• Movement of solutes across a membrane.

• Movement of water across a semi-permeable membrane.

• Movement of water that requires energy.

• Movement of large molecules through a cell membrane.

If a solution has a low water concentration, what does that imply about its solute concentration?

• It has a low solute concentration.

• It has a high solute concentration.

• Solute concentration is irrelevant to water concentration.

• It means there are no solutes present.

In a U-tube separated by a semi-permeable membrane, if Side B has a higher solute concentration than Side A, which direction will water initially move?

• From Side B to Side A.

• From Side A to Side B.

• Water will not move.

• Solutes will move from Side B to Side A.

What term describes a solution with a higher solute concentration compared to another solution?

• Hypotonic

• Isotonic

• Hypertonic

• Semi-permeable

Are you enjoying the video lesson?

• Yes

• No

What happens to red blood cells when placed in a hypotonic solution?

• They shrink

• They swell and possibly burst

• They remain stable

• They become hypertonic

What does an isotonic solution mean in terms of solute concentration?

• Higher solute concentration

• Lower solute concentration

• Equal solute concentration

• No solute concentration

If a saltwater fish is placed in freshwater, what would happen to its cells due to osmosis?

• They would shrink

• They would remain stable

• They would swell and possibly burst

• They would become isotonic

Which formula correctly represents water potential (Ψ)?

• Ψ = Ψs - Ψp

• Ψ = Ψp - Ψs

• Ψ = Ψp + Ψs

• Ψ = Ψs / Ψp
