Tannins Tannins
C
Resins
D
Gums
E
Latex Latex
Explanation: 

Detailed explanation-1: -In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury.

Detailed explanation-2: -Solution : Latex is a sticky, milky white substance secreted by plants.

Detailed explanation-3: -chicle, gum that consists of the coagulated milky latex of the sapodilla tree (Manilkara zapota), a tropical American fruit tree principally from Yucatán and regions of Central America.

Detailed explanation-4: -Diversity and Role of Latex in Plant Physiology. Latex is a milky emulsion produced by complex secretory structures called laticifers. It is defined as a suspension of various particles (organic and inorganic) dispersed in a liquid with different refractive index.

Detailed explanation-5: -Its chemical composition based on secondary metabolites such as alkaloids, cardenolides, phenolics, starch, furanocoumarins, sugars and non-protein amino acids, also proteins like compounds and rubber confers not only anti-herbivore effect to latex but antimicrobial properties.
