Question

Which one of the following is wrong about the digestive system of a grasshopper?

• A. Wall of crop is muscular and its lumen is lined with cutile.
• B. A pair of small, branched salivary glands associated to anterior end of midgut.
• C. Heptatic caecae are six pairs of glands associated to anterior end of midgut.
• D. Malpighian tibules are the thread-like tibules with blunt tips associated to the function of midgut and hindgut.

Answer 1

The correct option is A Wall of crop is muscular and its lumen is lined with cutile.

Grasshoppers have the typical insect body plan of head, thorax and abdomen.
The thorax and abdomen are segmented and have a rigid cuticle made up of overlapping plates composed of chitin. Hence, Wall of a crop is muscular and its lumen is lined with cutile is wrong about the digestive system of a grasshopper.

So, the correct option is 'Wall of the crop is muscular and its lumen is lined with cutile.'.
