Which of the following waste products in plants is excreted through the stomata and lenticles?

The waste product in plants that is excreted through the stomata and lenticles is carbon dioxide. Plants take in carbon dioxide through the stomata and lenticles during the process of photosynthesis, where it is used as a source of carbon to make food. The oxygen produced during photosynthesis is released back into the air through the stomata and lenticles, while the excess carbon dioxide is excreted. This helps regulate the plant's internal carbon dioxide levels and maintain a healthy balance of gases in the plant's cells. On the other hand, alkaloids, tannins, and anthocyanins are all compounds produced by plants, but they are not excreted through the stomata and lenticles. Instead, they serve various functions in the plant, such as protecting it from predators and disease, attracting pollinators, and providing color and flavor to fruits and flowers.
