Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -Plants simply undergo photosynthesis first as a way to make glucose.

Detailed explanation-3: -Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-4: -The primary fuel for cellular respiration is a molecule of glucose, which is used to make energy. In the cellular world, energy is a charged molecule with three phosphate groups called adenosine triphosphate (ATP).

Detailed explanation-5: -Thus, during photosynthesis a plant consumes water, carbon dioxide, and light energy, and produces glucose and oxygen. The sugar glucose is important because it is necessary for cellular respiration.
