Arthropods have mosaic vision. Give reason.

Explanation

**Step-by-Step Solution:**

1. **Understanding Mosaic Vision**: Mosaic vision refers to the way in which certain animals perceive their environment through multiple images that are combined to form a single view. This type of vision is characterized by the ability to see a wide field of view but with less detail compared to other types of vision.

2. **Presence of Compound Eyes**: Arthropods, such as insects and crustaceans, possess compound eyes. These eyes are made up of numerous small units called ommatidia, each of which contains its own lens.

3. **Structure of Ommatidia**: Each ommatidium has a hexagonal shape and contains a lens that focuses light onto photoreceptor cells. The hexagonal arrangement allows for a large number of these units to be packed together, maximizing the field of view.
