With reference to reproduction in Hydra, consider the following statements: 1. New individuals develop as outgrowths called buds. 2. The buds formed in Hydra never detach from the parent body. 3. This is a form of sexual reproduction. Which of the statements given above is/are correct?

The correct option is (a) 1 only. Explanation Hydra reproduces asexually through a process known as budding. In this method, a new individual develops from an outgrowth or bud due to repeated cell division at a specific site. - Statement 1 is Correct: In Hydra, new individuals develop as outgrowths called buds. These buds develop into tiny individuals while initially attached to the parent organism. - Statement 2 is Incorrect: The buds do not remain attached permanently. Upon maturation, the bud constricts at the base and detaches from the parent body to become a new, independent individual. - Statement 3 is Incorrect: Budding is a form of asexual reproduction. It involves a single parent and occurs without the formation or fusion of gametes. Key Takeaway: Budding in Hydra is a classic example of asexual reproduction where a specific site on the parent body undergoes repeated cell division to form an outgrowth (bud) that eventually separates to live independently.

Solution

The correct option is (a) 1 only.

Explanation

Hydra reproduces asexually through a process known as budding. In this method, a new individual develops from an outgrowth or bud due to repeated cell division at a specific site.

Statement 1 is Correct: In Hydra, new individuals develop as outgrowths called buds. These buds develop into tiny individuals while initially attached to the parent organism.
Statement 2 is Incorrect: The buds do not remain attached permanently. Upon maturation, the bud constricts at the base and detaches from the parent body to become a new, independent individual.
Statement 3 is Incorrect: Budding is a form of asexual reproduction. It involves a single parent and occurs without the formation or fusion of gametes.

Key Takeaway: Budding in Hydra is a classic example of asexual reproduction where a specific site on the parent body undergoes repeated cell division to form an outgrowth (bud) that eventually separates to live independently.
