Important Long Question Answer
Q.1. Describe the process of the formation of yam from cotton wool.
Ans. Cotton wool is obtained from cotton plants. The cotton plants are grown in fields. They are usually grown in places having black soil and a warm climate. The fruits of the cotton plants called cotton bolls are about the size of lemons. After maturing, the bolls burst open and seeds covered with cotton fibres can b,e seen. From the cotton bolls cotton is picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning of cotton. It is done by hand or by machines. These fibres are then converted into yam.
Q.2. Describe the process of spinning and weaving.
Ans. Spinning: The process of making yarn from fibres is called spinning. In this process, fibres from a mass of cotton wool are drawn out and twisted. By this fibres come together to form a yarn. Spinning can be done by hand, by Takli and Charkha. On a large scale, spinning is done with the help of machines.
Weaving: The process of arranging two sets of yarns together t6 make a fabric is called weaving. The process of weaving can be done on looms. The looms are either-hand operated or power operated.
