NEET BIOLOGY

Detailed explanation-1: -Photosynthesis involves several different chemical reactions, but these can be summarised in two main stages. In the first reaction, energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product.

Detailed explanation-2: -Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.

Detailed explanation-3: -The chemical reaction which takes place in photosynthesis involves combining of water and carbon dioxide to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.

Detailed explanation-4: -Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.

Detailed explanation-5: -Final answer-Photosynthesis is a chemical change.
