Mention the special features of the eye in a cockroach.
Answer- The special features of the eye of a cockroach are listed below:
- The cockroach eye is composed of multiple photoreceptor units.These units are called ommatidia.
- Every ommatidium constructs an image of the object seen.Therefore, all the ommatidia together form a mosaic of images of the object seen.
- These compound eyes have a large view angle and can help detect small activities by a single glance.
- However, the resolution of the images formed is not of good quality as compared to a simple eye.
