Assertion : Petroplants produce large amount of latex.

Reason : The latex contains long chain hydrocarbons.

  • If both assertion and reason are true and reason is the correct explanation of assertion

  • If both assertion and reason are true but reason is not the correct explanation of assertion

  • If assertion is true but reason is false

  • If both assertion and reason are false

Solution

A.

If both assertion and reason are true and reason is the correct explanation of assertion

Latex of some plants containing long chain hydrocarbons is considered to be a good substitute for liquid fuels or petroleum. Therefore, plants having large amount of latex with long chain hydrocarbons are known as 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 hydrocarbons. Their hydrocarbon contents can be increased by genetic manipulations (genetic engineering). But commercial production of petroleum or liquid fuel alternative (through petroplants) is in early stage. The use of these petroplants may reduce the pressure on liquid fuel or petroleum.
