Question

part 3: label the diagrams of cells using the following terms: diffusion, active transport, osmosis, equilibrium. the arrows show the direction of transport. you may use the terms more than once! high co₂ levels low co₂ levels 8 h₂o molecules 2 h₂o molecules 25 glucose molecules 5 glucose molecules 2 h₂o molecules 8 h₂o molecules high protein levels low protein levels 10 h₂o molecules 10 h₂o molecules

Explanation:

1. For the first diagram with CO₂: Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. CO₂ moves from high to low levels, so it is diffusion.
2. For the second diagram with water: Osmosis is the diffusion of water across a semi - permeable membrane. Water moves from an area with more water molecules (lower solute concentration) to an area with fewer water molecules (higher solute concentration), so it is osmosis.
3. For the third diagram with glucose: Active transport moves molecules against the concentration gradient (from low to high concentration) and requires energy. Glucose moves from low to high levels, so it is active transport.
4. For the fourth diagram with water: Osmosis as water moves from high to low water - molecule area (higher to lower water potential).
5. For the fifth diagram with protein: Diffusion as protein moves from high to low levels.
6. For the sixth diagram with water: Equilibrium is reached when there is no net movement of water molecules as the number of water molecules on both sides is the same.

Answer:

1. Diffusion
2. Osmosis
3. Active transport
4. Osmosis
5. Diffusion
6. Equilibrium
