Question

Which of the following plant yields oil and fibre both?

A) Cocos nucifera
B) Eucalyptus
C) Brassica campestris
D) Euphorbia hirta

Answer 1

Hint It is an edible fruit that is from a tree of the palm family. Its flesh is high in fat and can be dried or eaten fresh or can also be processed into coconut milk or coconut oil. The liquid in the coconut is called coconut water and it is used in many beverages.
Complete Step-by-step answer:
Cocos nucifera is the scientific name of coconut. It is an excellent source of healthy fats, nutrients, and antioxidants. Raw coconut is high in fibre so it is also used to prevent constipation. Eating raw coconut before sleep can prevent health diseases.
Eucalyptus ointments are used on the nose and chest to relieve congestion. It also produces oil and its oil helps to loosen phlegm, so many people breathe in eucalyptus steam to help treat bronchitis, coughs, and the flu.
Brassica campestris is the scientific name of mustard. It produces mustard oil that we generally use in our homes to cook food. It produces rapeseed oil which is a vegetable oil taken from this plant. This can also be used in skincare products to help nourish and replenish skin.
Euphorbia hirta is also called the Asthma plant. Its leaves are mostly used for female disorders, respiratory ailments(cough, coryza, bronchitis, and asthma), worm infestations in children, dysentery, jaundice, and pimples.

Hence the correct answer is option A.
Note: The coconut water from the tender coconut that we mostly drink is nothing but free-nuclear endosperm made up of thousands of nuclei and the surrounding white kernel is the endosperm. The endosperm may be directly gobbled up by the embryo-like pea, groundnut, and beans before seed maturation or it may persist in the seed like castor and coconut.
