Detailed explanation-1: -Photosynthesis is the process that plants use in the presence of sunlight to convert carbon dioxide taken in by their leaves and water taken in through the roots to produce oxygen and sugar (glucose). This process takes place in the chloroplast of the plant cell with the presence of the green pigment of chlorophyll.

Detailed explanation-2: -In both cellular respiration and photosynthesis, chemiosmosis occurs. Chemiosmosis is the process in which the creation of a proton gradient leads to the transport of proton down its concentration gradient to produce ATP.

Detailed explanation-3: -During photosynthesis, plants trap light energy with their leaves. 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.

Detailed explanation-4: -Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration. Cellular respiration makes carbon dioxide and water (and ATP), which are the starting products (together with sunlight) for photosynthesis.

Detailed explanation-5: -The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.
