The correct Answer is:
To solve the problem, we need to analyze the two statements provided: **Statement A:** "In cockroach, vision is mosaic and apposition image is formed." **Statement B:** "Mosaic vision has less sensitivity and more resolution." ### Step-by-Step Solution: 1. **Understanding Statement A:** - Cockroaches have compound eyes made up of multiple units called ommatidia (around 2000 in a cockroach). - Each ommatidium contributes to the overall image, leading to a mosaic vision. - The type of image formed by the compound eye of a cockroach is indeed an apposition image. - Therefore, **Statement A is correct**. 2. **Understanding Statement B:** - Mosaic vision, as seen in organisms with compound eyes like cockroaches, is characterized by high sensitivity to light but lower resolution compared to simple eyes. - This means that while they can detect movement and changes in light effectively (high sensitivity), the detail of the image (resolution) is not as clear. - Thus, **Statement B is incorrect** because it states that mosaic vision has less sensitivity and more resolution, which contradicts the known characteristics of mosaic vision. 3. **Conclusion:** - Since Statement A is correct and Statement B is incorrect, the correct answer is that Statement A is true, and Statement B is false. ### Final Answer: - The correct option is: Statement A is correct, and Statement B is incorrect.
