Question

What is the nature of cotton seed?
a.Hairy
b.Solid
c.Light
d.Both a and b.

Answer 1

Hint: You must know the nature of the cottonseed and you must know that cotton is a seed-hair fibre made mostly of cellulose. About \[87\] to \[90\] percent of cellulose is composed of the fibres(a carbohydrate plant substance), water with \[5\] to \[8\] percent, and natural impurities are about $4$ to $6$ percent.

Complete answer:
The seed of cotton is covered by white, rusty and hairy fibres which are made of cellulose that make it light and help in its dispersal as it uses air as a medium.
So, 'Both A and C' are the correct option.
By weight, they are \[{\mathbf{32}}\% \] coat, \[{\mathbf{8}}\% \]embryonic root and shoot and\[\;{\mathbf{60}}\% \]cotyledon. These are \[20\% \] of protein, \[20\% \] of oil and \[3.5\% \] of starch. To form a ball of cotton lint these fibres grow from the seed coat. The seeds are pressed to make oil and used as ruminant animal feed and about \[15\% \] of the value of the crop

Option a is the correct answer.

Note:
The cotton seeds are \[3.5 - 10\] mm long and the cotton seeds are ovoid. It has the main product which is used to make cotton textiles, and shorter hairs as it is covered with white or rusty, long and woolly hairs, called the lint. The seed is about\[\;15 - 20\% \] of the value of the cotton crop.
