Question

In groundnut (Arachis hypogea) oil is stored in
A. Endosperm
B. Cotyledons
C. Embryo
D. Tuber

Answer 1

Hint: Groundnut is a dehiscent legume plant that has storage material. The tiny halves of the seeds provide carbohydrates and proteins for the development of the embryo for its development during germination.

Complete answer-Groundnut or peanut is taxonomically known as Arachis hypogea. It is a legume crop that is commonly grown in tropics and subtropics. It is an annual herbaceous plant with lateral roots and nodules. It is an oilseed crop that contains up to $40 - 49\% $ of oil. It has calcium, phosphorus, iron, zinc, and boron. It also contains small quantities of vitamin E and vitamin B complex. They are rich in thiamine and nicotinic acid. In groundnuts, the cotyledons and embryonic axis are zygotic tissues. Oil is stored in the cotyledons of groundnut, which have stored food reserves that are used during the initial stages of growth.
Hence, the correct option is B Cotyledons.

Note: Cotyledons are two fleshy halves that provide nutrition to the embryo for its development into a seedling with functional roots and small photosynthetic leaves. The seeds contain two fleshy parts that contain embryos or baby plants. Cotyledons provide energy for the process of germination. Germination requires moisture and temperature. Groundnut is a type of climbing vine that is distantly related to the soybean. It also has high niacin and folate content. It is also considered an energy-dense food. It grows from the root system.
