1.	Photosynthesis process provides food for all organisms. It mainly takes place by two phases. Light reaction is first phase. H2O → H + OH Above equation in light reaction shows what?
Answer» 1. The first phase of photosynthesis is light reaction. It occurs in grana of the chloroplast. 2. During this phase light-activated chlorophyll molecule splits water molecule intoHydrogen (H⁺) and Hydroxyl ions (OH^- ) 3. This reaction is known as photolysis of water which means splitting by light (photo means light, lysis means breaking). This was discovered by Hill. Hence it is also called Hill’s reaction.
