Question

Which among these is not involved in excretion in cockroaches?
A. Malpighian
B. Nephrocytes
C. Uricose glands
D. Maxillary palps

Answer 1

Hint: The primary performance of the excretion in cockroach occurred by Malpighian tubules, and tubules are attached with the ciliated cells and glandular. The uric acid which is excreted out through the hindgut produced by the absorption of nitrogenous waste products. In the excretion urecose glands, nephrocytes and fatty bodies are present in it. For antennae and cleaning maxillary palps are used in the front pair of the legs.

Complete answer:
Cockroaches are the omnipresent type of animal that is found in the dark damp places such as manholes, kitchen and stores. They come out for feeding at night and are a kind of nocturnal. During the day time they hide themselves in the cervecies and cracks under the cupboard etc. Cockroaches are omnivorous and feed on all animals and plant material. They are fast runners because of the cursorial nature and have wings that help to fly but rarely do they exhibit their ability to fly. Maxillae is a pair of structures that are present in the arthropods on the head and mouthparts and help to use for manipulating and taste the food.

Therefore the correct option is (D).

Note: In the cockroach flame cells present in the platy helminth, nephridia and Malpighian tubules are the excretory organs in the cockroach. And with the help of Malpighian tubules excretion occurred in the cockroach. And Malpighian tubules found in the medium intestine and posterior intestine present with the function of loose body cavity and free in the distal end that are attached through the perinephric membrane.
