The main result of photosynthesis is in the chemical process of photosynthesis, water is a a) catalyst b) enzyme c) product d) reactant

Hi there,
Chlorophyll plays a vital role by absorbing sunlight of a range of wavelengths, primarily blue and red. It is a catalyst for photosynthesis - increasing the speed of the reaction by taking part in it but remaining unchanged at the end.

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem

We are not able to see the stars. light prevents our seeing the stars. i hope it kinda : )
