Which of the following is correct for mosaic vision in cockroach?
1 It is with more sensitivity but has less resolution
2 With the help of several ommatidia, a cockroach receives several images of an object
3 Being common during night, it is called nocturnal vision also
4 All of the above
Explanation:
All the statements are correct. compound eyes of cockroaches are situated at the dorsal surface of the head. Each eye consists of about 2000 hexagonal ommatidia (sing.: ommatidium). With the help of several ommatidia, a cockroach can receive several images of an object. This kind of vision is known as mosaic vision with more sensitivity but less resolution, being common during night (hence called nocturnal vision).
