Secondary metabolites are toxic chemicals in plants that are not used in or derived from photosynthesis or respiration. what are the most probable function of secondary metabolites?

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

Secondary metabolites are produced mostly by the plants for the defense purposes. They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.
