Detailed explanation-1: -Glucose is the main product, while oxygen is the by-product of photosynthesis.

Detailed explanation-2: -Glucose is the end-product of carbohydrate digestion, absorbed by enterocytes. Increased blood glucose concentrations occur 2 to 4 hours after a meal in simple-stomached animals. Gluconeogenesis and glycogenolysis within hepatic cells produce glucose when metabolically necessary.

Detailed explanation-3: -Plants make sugar by using energy from sunlight to transform carbon dioxide (CO2), a gas absorbed from the air, and water (H20) taken from the ground by roots into glucose (C6H12O6) and oxygen (O2). This process is called photosynthesis and occurs in the chloroplast of the plant cell.

Detailed explanation-4: -The first product of photosynthesis is sugar and it is converted into starch in all plants. The initial process of photosynthesis is the decomposition of water into oxygen, which is released and hydrogen. Direct light is required for this process.

Detailed explanation-5: -Glucose and oxygen (formed during splitting of water) are the final products of photosynthesis.
