What happens to the rate of photosynthesis when light intensity increases beyond a certain point?

• It continues to rise

• It plateaus / levels out

• It decreases

• It stops completely

How does temperature affect the enzymes involved in photosynthesis?

• Enzymes function optimally at any temperature

• Low temperatures increase enzyme activity

• High temperatures enhance enzyme activity

• Enzymes function optimally within a specific temperature range

What is the effect of water scarcity on photosynthesis?

• It increases the rate of photosynthesis

• It has no effect on photosynthesis

• It limits the rate of photosynthesis

• It enhances the intake of carbon dioxide

Why might plants close their stomata (pores) when water is limited?

• To increase the rate of photosynthesis

• To conserve moisture

• To enhance enzyme activity

• To increase light absorption
