04.1D Transport in Plants & Animals (PART D)

How does distance affect the rate of diffusion?

• Shorter distances increase the rate

• Greater distances increase the rate

• Distance does not affect the rate

How does the concentration gradient affect diffusion?

• The greater the concentration difference the faster the rate
• The smaller the concentration difference the faster the rate
• The greater the concentration the slower the rate

How does surface area affect the rate of diffusion?

• Greater the surface area the slower the rate 
• Greater the surface area the faster the rate
• Smaller the surface area the faster the rate
• Surface area does not affect diffusion

How does increasing temperature affect the rate of diffusion?

• Increases enzyme activity increasing the rate
• Gives molecules more energy increasing the rate
• Takes energy away from molecules slowing down the rate
• Decreases enzyme activity and decreases the rate
