DENDROLOGY

Detailed explanation-1: -Oxygen is not essential for the process of photosynthesis because oxygen is released in this process when plants utilize the raw materials i.e., carbon dioxide and water to produce sugars (glucose). Hence, it is not essential to carry out the process of photosynthesis.

Detailed explanation-2: –Sugars such as glucose and fructose are the end product of the method of photosynthesis. Two reactions take place in photosynthesis.

Detailed explanation-3: -chlorophyll: Any of several green pigments found in plants that perform photosynthesis-creating sugars (foods) from carbon dioxide and water. chloroplast: A tiny structure in the cells of green algae and green plants that contain chlorophyll and creates glucose through photosynthesis.
