Factor affecting photosynthesis

What is the correct equation for photosynthesis?

• Carbon Dioxide + Water + Light --> Glucose + Oxygen
• Light + Carbon Dioxide --> Water + Glucose + Oxygen
• Carbon Dioxide + Glucose + Light --> Water + Oxygen

Which of these will not affect photosynthesis?

• Light
• Temperature
• Glucose Availability
• Carbon Dioxide

What is a limiting factor?

• The factor which increases the rate of a reaction
• The factor that limits the reaction rate
• The factor that limits the rate at which an enzyme is destroyed

Which lettered graph represents the effect of temperature on photosynthetic rate?

• A

• B

• C

• D

How does temperature affects photosynthesis rate?

• As temperature increases, photosynthesis rate also increases.
• As temperature decreases, photosynthesis rate also decreases.
• Plants cannot photosynthesis if the temperature is too cold or too hot. 
• All of the statements are true.

How can greenhouses increase the rate of photosynthesis?

• Controlling and trapping heat to increase photosynthesis
• Stopping rainfall affecting plant growth
• Surrounding plants in the colour green makes them more likely to photosynthesise
• Plants are only given what they need instead of just taking everything they can find

What will happen to the photosynthesis rate if you increase the intensity of light?

• Photosynthesis rate will increase.
• Photosynthesis rate will decrease.
• Photosynthesis rate will remain the same.
• Photosynthesis will stop.

Which lettered graph represents the affect of light intensity on photosynthetic rate?

• A

• B

• C

• D

If a plant receives more carbon dioxide, what happens to the rate of photosynthesis?

• Increases
• Decreases
• Stays the same

Which lettered graph represents the effect of carbon dioxide gas on photosynthetic rate?

• A

• B

• C

• D
