DENDROLOGY

Detailed explanation-1: -Glucose is the simple food which is prepared first in the process of photosynthesis. Glucose and oxygen (formed during splitting of water) are the final products of photosynthesis.

Detailed explanation-2: -Glucose is a major by-product of photosynthesis. Some of the products which plants utilize glucose to synthesize cellulose, which is a necessary cell wall component and starch which is a food source for seeds. Plants also use glucose in their cellular respiration process to synthesize ATP.

Detailed explanation-3: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).
