Step-by-step solution
Latex of some plants containing long chain hydrocarbons is considered to be a good substitute for liquid fuels or petroleum. Such plants having large amount of latex with long chain hydrocarbons are called petroplants. Cultivation of petroplants is also a part of energy-cropping. The most common petroplants belong to families of euphorbiaceae, asclepiadaceae, apocynaceae, compositae, labiatae, sapotaceae, urticaceae, etc., which have property of converting large amounts of their photosynthates into latex with hydro
