Malpighian Tubules of Cockroach
Which of the following cells lines the malpighian tubules of a cockroach? The cockroach does not have a sense organ; instead, it relies on a set of organs to carry out these functions. A cockroach has six rectal papillae, which help it to absorb water and salts. The cockroach also has digestive enzymes called zymase and amylase. Most of the food it consumes is digested in the crop, and most of the nutrients are absorbed in the mesenteron. Moreover, a cockroach has a double ventral nerve cord that bears three ganglia in the thorax, and six in the abdomen.
The Malpighian tubules of cockcock are lined with which of the following cells: stellate cells, oxalate cells, and granules. Among the insect orders, the Malpighian tubules are known for their complex cycling systems. They are used by hemipterans to transport solutes, and reabsorb toxins and essential ions. Moreover, the tubules of the Coleoptera and Lepidoptera are embedded in a fat tissue surrounding the rectum. This arrangement is thought to improve the efficiency of solute processing.
The Malpighian tubules of Drosophila have two pairs, the right pair projects forwards from the hindgut, and the left pair extends backward to the posterior part. The tubule pairs then unite to form a common ureter, which enters the intestine between the hindgut and the midgut.
