With reference to the processing of cotton, consider the following statements: 1. Ginning is the process of separating fibres from the seeds by combing. 2. Ginning can only be done by machines and not by hand. 3. The cotton bolls burst open after maturing to reveal seeds covered with fibres. Which of the statements given above is/are correct?

Correct Option The correct option is (c). Explanation Cotton is a soft, fluffy staple fibre that grows in a boll, or protective case, around the seeds of the cotton plants. The processing of harvested cotton involves separating the useful fibre from the plant seeds to prepare it for spinning into yarn. Statement-wise Analysis - Statement 1 is Correct: Ginning is the process of separating cotton fibres from the seeds. This is achieved by combing the harvested cotton, which pulls the fibres away from the seeds. - Statement 2 is Incorrect: Ginning is not restricted to machines. Traditionally, ginning was done by hand using combs. While machines are predominantly used in modern industry for efficiency, the process can still be performed manually. - Statement 3 is Correct: The fruits of the cotton plant are called cotton bolls. Upon reaching maturity, these bolls burst open, revealing the seeds covered with soft white cotton fibres. Key Takeaway: Ginning is the mechanical separation of cotton fibres from seeds, a process that occurs after the cotton bolls mature and burst open.

Solution

Correct Option

The correct option is (c).

Explanation

Cotton is a soft, fluffy staple fibre that grows in a boll, or protective case, around the seeds of the cotton plants. The processing of harvested cotton involves separating the useful fibre from the plant seeds to prepare it for spinning into yarn.

Statement-wise Analysis

Statement 1 is Correct: Ginning is the process of separating cotton fibres from the seeds. This is achieved by combing the harvested cotton, which pulls the fibres away from the seeds.
Statement 2 is Incorrect: Ginning is not restricted to machines. Traditionally, ginning was done by hand using combs. While machines are predominantly used in modern industry for efficiency, the process can still be performed manually.
Statement 3 is Correct: The fruits of the cotton plant are called cotton bolls. Upon reaching maturity, these bolls burst open, revealing the seeds covered with soft white cotton fibres.

Key Takeaway: Ginning is the mechanical separation of cotton fibres from seeds, a process that occurs after the cotton bolls mature and burst open.
