The correct Answer is:
To answer the question regarding which molluscan group has an eye that resembles the vertebrate eye, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Groups of Mollusca**: - The question provides four options: Vivalia (Bivalvia), Gastropoda, Pelesipoda (also Bivalvia), and Cephalopoda. 2. **Analyze Vivalia (Bivalvia)**: - Bivalves, such as oysters, do not possess eyes. They have simple light-sensitive cells but no complex eyes. 3. **Analyze Gastropoda**: - Gastropods, like snails, have a pair of eyes. However, these eyes are structurally different from vertebrate eyes and do not resemble them closely. 4. **Analyze Pelesipoda (Bivalvia)**: - Similar to Vivalia, Pelesipoda (which includes clams and other bivalves) also do not have complex eyes. They lack the structures found in vertebrate eyes. 5. **Analyze Cephalopoda**: - Cephalopods, such as octopuses, have highly developed eyes that are structurally similar to vertebrate eyes. They possess an iris, a lens, and a large outer chamber, making their eyes quite advanced and comparable to those of vertebrates. 6. **Conclusion**: - Based on the analysis, the correct answer is **Cephalopoda**, as they have eyes that closely resemble vertebrate eyes. ### Final Answer: The eye of the molluscan group that resembles the vertebrate eye is **Cephalopoda**. ---
