Plants produce a wide variety compounds. These compounds are commonly referred to as Primary Metabolites, Secondary Metabolites, and Hormones. A) Briefly, discuss the roles that each of these types of compound plays in a Plant. In examinations of Secondary compounds, studies have identified that the expression of Secondary compounds can change over time or between populations of the same species. B) Why would this variability in Secondary compound expression be important to the survival of a Plant. The 3 major classes of Secondary compound discussed in lecture are Terpenes, Alkaloids, and Phenolics (Flavonoids). C) In terms of structure, what are the primary differences that could be used to classify each type of Secondary compound.
