Which type of vision is found in cockroach ?

Options

A. Binocular
B. Monocular
C. Panaromic
D. Mosaic

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the type of vision found in cockroaches.

2. **Understand Cockroach Anatomy**: Cockroaches have a body divided into three main parts: the head, thorax, and abdomen. The head contains important sensory organs.

3. **Locate the Eyes**: On the dorsal part of the head, cockroaches possess compound eyes, which are crucial for their vision.

4. **Structure of Compound Eyes**: Each compound eye of a cockroach is made up of approximately 2000 hexagonal units known as ommatidia. These units work together to form images.

5. **Function of Ommatidia**: The ommatidia create multiple images of a single object, which are then assembled to form a compound image.

6. **Type of Vision**: The type of vision produced by these compound eyes is referred to as "mosaic vision." This vision allows for high sensitivity but low resolution.

7. **Characteristics of Mosaic Vision**:
- **High Sensitivity**: This characteristic is beneficial for nocturnal animals like cockroaches, enabling them to see well in low light conditions.
- **Low Resolution**: This means that while they can detect movement and shapes, they may not see images clearly.

8. **Evaluate Answer Options**: The question may provide multiple-choice answers.
- **Option A: Binocular Vision** - Incorrect, as this involves two eyes seeing a single object.
- **Option B: Monocular Vision** - Incorrect, as this involves each eye seeing in different directions.
- **Option C: Panoramic Vision** - Incorrect, as it involves a wide field of view but not the specific structure of cockroach eyes.
- **Option D: Mosaic Vision** - Correct, as this is the type of vision found in cockroaches.

9. **Conclusion**: The correct answer to the question is that cockroaches have mosaic vision.
