(A) Polymeric substances
Cellulose:-Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Cellulose is the most abundant organic polymer on Earth.
Rubber:- Rubber is an example of an elastomer type polymer, where the polymer has the ability to return to its original shape after being stretched or deformed. The rubber polymer is coiled when in the resting state.
Gum:- Gum-producing structures of wood and bark. Plant gums are generally complex carbohydrate polymers that may also include hydroxyproline-rich proteins, resins, or other components and can be either soluble, partly soluble, or insoluble.
