Question

Assertion (A): Cnidoblasts (stinging cells) occur over the tentacles in Coelenterates.

Reason (R): They help in attachment and paralyzing the prey.

विकल्प

• Both A and R are true and R is correct explanation of the assertion.

• Both A and R are true but R is not the correct explanation of the assertion.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is correct explanation of the assertion.

Explanation:

Both statements are true. Cnidoblasts on the tentacles contain nematocysts, which help hold prey and can paralyse it by injecting poison; therefore, the reason correctly explains the assertion.
