What happens to photosynthesis if the temperature is too hot?

• It will denature the enzymes and photosynthesis will stop working

• It will damage the chlorophyll and photosynthesis will stop working.

• Nothing, photosynthesis will get even better

• The plant will start using oxygen to make glucose

• Nucleus

• Mitochondria

• Chloroplast

A scientist tries to use different colored lights to grow her plants. She notices that the green light does not work as well as the other colors. Why?

• Chlorophyll absorbs only green light

• Plants are already green and don't need green light

• Chlorophyll absorbs red and blue but reflects green light

• The color light in which plants absorb for photosynthesis is random
