Quick Summary

Secondary metabolites are compounds produced by plants that are not directly involved in their normal growth, development, or reproduction. Instead, they often serve defensive roles, such as deterring herbivores or protecting against pathogens. These compounds can also play a role in attracting pollinators.12

Plant anatomy refers to the study of the internal structure of plants. This includes examining cells, tissues, and organs to understand how they function and contribute to the plant's overall life processes. Secondary metabolites are synthesized through various metabolic pathways within the plant's cells.2

…found in the production of secondary compounds, such as alkaloids, quinones, essential oils, and glycosides. Angiosperms have evolved a comprehensive array of unpalatable or toxic secondary plant compounds that protect the plants from foraging herbivores. Some insects, however, successfully store these secondary compounds in their tissues and use them as…

…to its arsenal of defensive secondary metabolites. While it lacks the iridoid compounds found in other orders of the core asterid lineage of flowering plants, Asteraceae heavily exploits polyacetylenes, bitter sesquiterpenes (especially sesquiterpene lactones), terpenoid volatile oils, latex, several kinds of alkaloids (notably pyrrolizidine alkaloids in the tribe Senecioneae), and…
