Question

Choose the organ that has the same function as that of the microvilli present in the intestinal epithelium matched with the correct organism in which it is present.

• A. Malpighian tubules - Earthworm
• B. Typhlosole - Earthworm
• C. Hepatic caecae - Cockroach
• D. Intestinal caecae - Cockroach

Answer 1

The correct option is B Typhlosole - Earthworm

In the intestine of human alimentary canal, the microvilli which is present increases the absorptive surface area. Similarly, the intestinal lining of earthworm is folded to form villi. One of these villi becomes large and well developed than the others to form the typhlosole. The folded portion increases the surface area for the absorption of food in the intestine of earthworm.
Typhlosole is an internal fold of the dorsal wall of intestine in earthworm. Typhlosole is present between the 26th-95th segments.
The intestinal caecum in earthworms produce amylase which helps in digestion of starch.
The hepatic caecae in cockroaches secrete digestive juices which facilitates digestion.
The malpighian tubules are associated with the excretion of nitrogenous waste in cockroaches.
