Compare the concentrations of the sugar in the cell and the solution.  Which is HYPOTONIC?

• Cell
• Solution

What do the following terms have in common?
-diffusion
-osmosis
-facilitated diffusion

• They require energy to move materials
• They move from a low concentration to a high concentration
• They move move materials DOWN the concentration gradient
• They require ATP

Which direction will the dots (solute) move without the use of energy?

• into the cell
• out of the cell

Facilitated diffusion is the movement of materials into and out of the cell

• with the use of energy
• with the use of proteins but no energy
• by moving water
• by using ATP

The  movement of water from a high concentration to a low concentration is called

• diffusion
• osmosis
• facilitated diffusion
• active transport

The diagram represents a specialized cell located in the root of a plant. The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell.
Which choice correctly identifies the process responsible for the movement of each type of molecule represented in the diagram?

• Water = diffusion
  Oxygen = active transport
• Water = diffusion
  Oxygen = diffusion
• Water = active transport
  Oxygen = active transport
• Water = active transport
  Oxygen = diffusion

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

The water level increases on the right because

• there are less particles on the right
• there are more particles on the right
• the right side is hypotonic
• the right side is isotonic
