Solution

Petroplants are plants having large amount of latex with long chain hydrocarbons. Latex of these plants are a good substitute for liquid fuels or petroleum. Cultivation of petroplants is a part of energy- cropping. Dr. Calvin was the scientist who identified petrocrops. They have property of converting large amount of their photosynthates into latex along with hydrocarbons. Some important petrocrops are Euphorbia antisyphilitica, E. lathyris Calotropis procera etc
