What type of vision is found in cockroaches?(A) Mosaic(B) Super position(C) Binocular(D) None of them

The correct answer is (A) Mosaic vision.

Detailed Explanation:
Cockroaches possess mosaic vision, which is typical of many arthropods, including insects. This type of vision is due to the structure of their compound eyes, which consist of numerous small visual units called ommatidia. Each ommatidium captures a part of the image, and together, these units create a mosaic-like image in the brain.

Here are the characteristics of mosaic vision:

Low resolution: Since each ommatidium captures a small part of the environment, the overall image lacks fine details.
Sensitive to movement: Although the resolution is low, cockroaches can detect quick movements very efficiently, which helps them avoid predators.
Nocturnal adaptation: Mosaic vision works well in dim light, making it ideal for nocturnal creatures like cockroaches.
The other options:

(B) Superposition vision is seen in nocturnal insects like moths, where multiple ommatidia contribute to a single visual perception.
(C) Binocular vision is found in animals like humans and predators, where both eyes focus on the same point to give depth perception.
(D) None of them is incorrect because cockroaches clearly have mosaic vision.
