Long Answer Questions
24) A cotton shirt, before it reaches you, completes a long journey. Elaborate this journey starting from cotton bolls.

The fruits of cotton plants are known as cotton bolls. These bolls of cotton are having the size equal to lemon. These cotton bolls burst after maturing due to heat. These opened cotton bolls have the seeds covered with cotton fibres. Then these fibres are removed and these are sent to the factories. In the factories the further process of ginning is started. Ginning is the separation of fibre and combing process of cotton. Further making of yarn from fibre takes place. Cotton Yarn is made into cotton fabric which is then used to make cotton shirts.
