EXPLANATION: Green gland is excretory organ of some arthropods. Green gland is located near the base of larger antennae, that is why, it is also called as antennal gland. Amphids and phasmids are present in nematodes. They are the sense organs of nematodes. These organs are used to detect or sense various chemicals. Ctenidia is a respiratory organ of many mollusks. This organ is also present in gastropods, cephalopods and polyplacophorans. Poison claw is a venom producing gland, which is present at the base of the fangs. It is present in centipedes. This poison claw is the modified form of first leg to protect the body against the predators. Conchiolin is a tough protein, which is secreted by mollusks. It forms the organic matrix of the shell.
