Cell Transport

What do the following terms have in common?

-diffusion

-osmosis

-facilitated diffusion

• They require energy to move materials

• They move from a High concentration to a Low concentration

• They move move materials DOWN the concentration gradient

• They require ATP

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

• out of the cell

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

• active transport

Semi-permeable mean to allow

• all materials across the membrane

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.
