The correct Answer is:
To solve the matching question regarding the reproductive structures of a cockroach, we will analyze each term and match it with the correct description provided. ### Step-by-Step Solution: 1. **Phallomere (A)**: - The phallomere is a structure found in male cockroaches that surrounds the male gonopores. It is part of the external genitalia. - **Match**: (iv) The external genitalia. 2. **Gonopore (B)**: - The gonopore is the opening of the ejaculatory duct in male cockroaches. It is where the sperm is expelled from the reproductive system. - **Match**: (iii) Opening of the ejaculatory duct. 3. **Spermatophore (C)**: - A spermatophore is a container that carries sperm. In cockroaches, it is used for indirect sperm transfer and is produced by specialized glands in males. - **Match**: (ii) Bundles of sperm. 4. **Ovarioles (D)**: - Ovarioles are the structures in female cockroaches that contain developing ova. Each ovary consists of multiple ovarioles. - **Match**: (i) Chain of developing ova. ### Final Matches: - A. Phallomere → (iv) The external genitalia - B. Gonopore → (iii) Opening of the ejaculatory duct - C. Spermatophore → (ii) Bundles of sperm - D. Ovarioles → (i) Chain of developing ova ### Correct Option: The correct option for the matches is: - A - iv - B - iii - C - ii - D - i ---
