Question

In pulses, protein is stored in
A) Cotyledons
B) Endosperms
C) Pericarp
D) Seed coat

Answer 1

Hint: Proteins are the important macromolecular component of our balanced diet as they are the rich source of amino acids.

Complete Answer:
Pulses are the rich source of nutrition in a vegan’s diet. Black lentils, green lentils, split peas, navy beans, chickpeas, black beans, kidney beans, etc are high protein pulses to be included in our daily diet.

A) Option a: This is a significant portion of the plant embryo enclosed within a seed. To examine the cotyledons, one needs to remove off the seed coating. The embryo bulk comprises two large and white kidney-shaped cotyledons which are the sac-like structure for storing the reserve food material. These reserved food materials are stored here in the form of carbohydrates and proteins which provides nourishment to the growing embryonal axis. Therefore, this is the correct option.

B) Option b: Endosperm is a tissue produced within the plant seed and provides nutrition to the growing plants in the form of starch. Thus, this is the incorrect option.

C) Option c: The pericarp is defined as that part of the fruit which is formed from the wall covering of the ripened ovary. Thus, this is the incorrect option.

D) Option d: The seed coat is the outer protective covering of the seed also known as testa. Thus, this is the incorrect option.

Thus, the correct option is a) Cotyledons.

Note: The total count of the cotyledons present within a single plant works as the functional basis for the botanical classification of the plant.
