NEET BIOLOGY

Detailed explanation-1: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

Detailed explanation-2: -The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis. Cellular respiration occurs in plant and animal cells. Plants use sunlight during photosynthesis to convert energy from the sun in order to manufacture sugar and the chemical energy ATP and to release oxygen.

Detailed explanation-3: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-4: -The aerobic cellular respiration uses oxygen as terminal electron acceptor. So glucose and oxygen are the product of photosynthesis which is used in cellular respiration. So, the correct answer is option D.
