Cell Transport

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

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

In this situation, where the solute is illustrated by red dots, predict if will WATER move into or out of the cell, and how that will affect the cell.

• Water will move into the cell and the cell will expand.
• Water will move into the cell and the cell will shrink.
• Water will move out of the cell and the cell will expand.
• Water will move out of the cell and the cell will shrink.

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion
