Diffusion

Diffusion is the movement of particles from an area of?

• Low to high water potential

• High to low concentration

• Low to high concentration

• High to low water potential

If temperature increases, what happens to the rate of diffusion?

• Increases

• Decreases

• Stays the same

As we increase the temperature we are giving the particles more ............... energy so they diffuse more.

As we increase the surface area what are we doing to the rate of diffusion?

• Increasing

• Decreasing

• Stays the same

As we decrease the surface area to volume ratio, what are we doing to the rate of diffusion?

• Increasing

• Decreasing

• Stays the same

Large organisms such as humans have a .............. surface area to volume ratio

Small organisms such as protoctista have a ........... surface area to volume ratio

Which kingdom(s) contain only multicellular organisms

• Animals

• Plants

• Fungi

• Protoctista

Which kingdoms only contain unicellular organisms?

• Plants

• Fungi

• Protoctista

• Prokaryotes/bacteria

This kingdom can contain both unicellular and multicellular organisms
