Heya !!!
Crop is a distensible sac present in the alimentary canal of the cockroach...
It acts as reservoir for storing food...
Gizzard is the thick walled muscular structure present behind the crop...
It acts as both grinding mill and sieve ..as it grinds the food by the six powerful teeth present in it... And also it filters the food by the hairy pads with backwardly directed bristles present behind the teeth...
Tracheoles are the tubular extensions of the tracheoblast...
They contain the tracheolar fluid and help in transporting the oxygen to the cells of the tissue...
Compound eyes are sensory structures present in cockroach...
They act as photoreceptors...
Hope this helps you :)
