Quiz: Passive Transport

What is a semipermeable membrane?

• A semipermeable membrane allows all substances to pass freely.
• A semipermeable membrane is a membrane that allows certain substances to pass while blocking others.
• A semipermeable membrane is impermeable to all substances.
• A semipermeable membrane only allows gases to pass through.

What is diffusion?

• Diffusion is the process of particles moving randomly without any concentration gradient.
• Diffusion refers to the mixing of two substances in equal proportions.
• Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
• Diffusion is the transfer of energy from one particle to another.

What way does the concentration gradient go?

• From low concentration to equal concentration
• From equal concentration to high concentration
• From high concentration to low concentration

• True
• False

What is osmosis?

• Osmosis refers to the movement of nutrients into cells.
• Osmosis is the diffusion of gases across a membrane.
• Osmosis is the process of energy production in cells.
• Osmosis is the movement of water across a membrane due to concentration differences.

What happens in an isotonic solution?

• Water moves into the cell, causing it to swell.
• There is no net movement of water; the cell remains stable.
• The cell loses water and shrinks.
• The cell bursts due to excess water intake.

What happens in an hypotonic solution?

• Water moves into the cell, causing it to swell.
• There is no net movement of water; the cell remains stable.
• The cell loses water and shrinks.
• The cell bursts due to excess water intake.

What happens in an hypertonic solution?

• Water moves into the cell, causing it to swell.
• There is no net movement of water; the cell remains stable.
• The cell loses water and shrinks.
• The cell bursts due to excess water intake.

In the given scenario what will happen to the organism: salt is poured onto eggplant.

• Water will move out of the eggplant cells and the cells will shrink.
• Water will move out of the eggplant cells and the cells will swell.
• Water will move into the eggplant cells and the cells will swell.
