Document Summary
Rubber: tires, pencil eraser, protective equipment for the healthcare industry, sport balls, 37,000 plant species produce latex; 7000 contain rubber. Para rubber: (natural rubber) this is the inner bark where it serves as the latex containing rubber. Chicle : once a source of chewing gum. Rubber is produced within the latex of natural rubber plants. Latex: a milky substance (a suspension or emulsion in a liquid with a varying refractive index). A suspension where the components are not dissolved with a high refraction index- how long a liquid takes to move through it. Prickly lettuce: when the plant is wounded there is a white colour. Latex occurs in wither a series of cells (specialized cells) (articulated laticifers) or in a single cell (non-articulated laticifer) Euphorbia is a non articulated laticifer that has a tube like structure that carries latex. Suspended material in plant latex may include: rubber particles, waxes, proteins, essential oils, mucilage.
