Exploring Diffusion and Osmosis Concepts

What is the basic concept of diffusion?

• Movement of molecules requiring energy

• Movement of molecules from high concentration to low concentration

• Movement of molecules from low concentration to high concentration

• Movement of water molecules only

What type of transport system is diffusion?

• Osmotic transport

• Facilitated transport

• Passive transport

• Active transport

What is a solute?

• A substance that gets dissolved

• A substance that dissolves other substances

• A type of solution

• A type of solvent

In an isotonic solution, what happens to the cell?

• The cell shrinks

• The cell swells

• The cell maintains its normal size and shape

• The cell bursts

What happens to a cell in a hypotonic solution?

• The cell bursts

• The cell maintains its normal size and shape

• The cell shrinks

• The cell swells

What happens to a cell in a hypertonic solution?

• The cell swells

• The cell shrinks

• The cell maintains its normal size and shape

• The cell bursts

What is osmosis?

• Diffusion of any substance

• Movement of solutes

• Diffusion of water

• Active transport of water

In the example with a semi-permeable bag in 2% salt solution, what happens to the bag with 10% salt solution inside?

• The bag bursts

• The bag loses water

• The bag gains water

• The bag remains the same

Why does water move towards areas with more solute?

• Water is attracted to solute particles

• Water moves randomly

• Water moves to areas with less solute

• Water requires energy to move

What is the term for a solution with equal solute concentration inside and outside the cell?

• Osmotic

• Isotonic

• Hypertonic

• Hypotonic
