Osmosis and Solutions Quiz

What is the primary purpose of osmosis in biological systems?

• To decrease water concentration

• To create energy

• To balance solute concentration

• To increase solute concentration

In an isotonic solution, what is the relationship between the solute concentrations inside and outside the cell?

• No solute outside the cell

• Equal inside and outside the cell

• Higher outside the cell

• Higher inside the cell

What happens to a cell placed in a hypertonic solution?

• It bursts

• It remains the same

• It swells

• It shrinks

What is the term used to describe the shrinking of a cell in a hypertonic solution?

• Diffusion

• Crenation

• Lysis

• Osmosis

In a hypotonic solution, where does the net movement of water occur?

• Out of the cell

• Equally in and out

• Into the cell

• No movement

What is the potential outcome for a cell in a hypotonic solution if the water influx continues?

• It remains unchanged

• It becomes isotonic

• It bursts

• It shrinks

What is the process called when a cell bursts due to excessive water intake?

• Crenation

• Lysis

• Diffusion

• Equilibrium

Why is it dangerous to drink seawater when stranded at sea?

• It hydrates the body

• It provides essential nutrients

• It causes cells to swell

• It makes the blood hypertonic

What is the key to maintaining cell size and function in different solutions?

• Avoiding any solute

• Maintaining isotonicity

• Maintaining hypotonicity

• Maintaining hypertonicity

What happens to the blood when seawater is consumed?

• It becomes hypertonic

• It becomes hypotonic

• It becomes isotonic

• It remains unchanged
