Effect of increasing temp. on photosynthesis (up to optimal point)
Effect of increasing temp. on photosynthesis (up to optimal point)
Rate increases
Why does temp. affect photosynthesis rate?
Why does temp. affect photosynthesis rate?
Enzyme-controlled process
Effect of very high temp. on photosynthesis enzymes
Effect of very high temp. on photosynthesis enzymes
Enzymes denature, rate decreases
Effect of light intensity on photosynthesis
Effect of light intensity on photosynthesis
Higher intensity increases rate (until other factors limit)
