What chemicals do plants produce?

Plants produce a variety of chemicals, including primary metabolites like carbohydrates, proteins, and lipids, which are essential for growth and energy. Additionally, they synthesize secondary metabolites such as alkaloids, terpenes, and phenolics, which often play roles in defense against pests and diseases, attract pollinators, and contribute to plant flavor and aroma. These chemicals are crucial for both plant survival and their interactions with the environment.
