Osmosis and Its Impact on Living Organisms

What is the movement of water through a semi-permeable membrane called?

• Facilitated diffusion

• Osmosis

• Active transport

• Diffusion

In osmosis, water molecules travel from areas of ______ concentration to areas of ______ concentration.

• Solute, solvent

• Low, high

• High, low

• Equal, unequal

What is the term used to describe the side with a higher solute concentration in osmosis?

• Osmotic

• Hypotonic

• Hypertonic

• Isotonic

What is the formula for calculating water potential?

• Water potential = solute potential + pressure potential

• Water potential = pressure potential + solute potential

• Water potential = solute potential - pressure potential

• Water potential = solute potential x pressure potential

What is the function of turgor pressure in plant cells?

• To increase pressure potential

• To maintain cell shape and structure

• To prevent water movement

• To decrease solute concentration

What happens to red blood cells if they are placed in a solution with a lower solute concentration?

• They remain unchanged

• They multiply

• They shrink

• They burst

What is the effect of dumping salty ocean water into soil on plants?

• It can eventually kill plants

• It has no effect on plants

• It helps plants grow better

• It makes plants resistant to diseases

Why do saltwater fish have a higher solute concentration in their cells compared to freshwater?

• To increase pressure potential

• To adapt to their environment

• To maintain cell shape and structure

• To prevent water movement

What is the term used to describe the side with a lower solute concentration in osmosis?

• Hypotonic

• Osmotic

• Isotonic

• Hypertonic

What happens to plant cells when they are placed in a hypertonic solution?

• They burst

• They shrink

• They multiply

• They remain unchanged
