Is oxygen produced during light reactions of photosynthesis an excretory product of plants?

This oxygen can undoubtedly be referred to as a plant excretory product because it is not used by the plants during photosynthesis; rather, it is released as a consequence of photolysis during light reactions. This oxygen production serves as the primary means of resupplying atmospheric oxygen.

No, oxygen that is created during the light reactions of photosynthesis is released as a byproduct of the photosynthetic process and is not something that plants excrete.

No, oxygen produced during the light reactions of photosynthesis is not considered an excretory product of plants. Instead, it is a byproduct of the photosynthetic process. During photosynthesis, plants use light energy to convert carbon dioxide and water into glucose and oxygen. The oxygen released as a result of this process is typically released into the atmosphere as a waste product, but it is not considered excretory in the same way metabolic wastes are. Excretory products in plants typically include substances such as excess salts, minerals, or metabolic byproducts that are actively eliminated from the plant's cells. Oxygen, on the other hand, is a vital byproduct of photosynthesis that supports aerobic respiration in plants and other organisms.
