Assertion : Excretion in cockroach occurs by Malpighian tubules Reason : Each Malpighian tubule collect \(\mathrm{N}_{2}\) wastes as urea
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Excretion in cockroach is performed by Malpighian tubules, each tubule is lined by glandular and ciliated cells. They absorb nitrogenous waste product and convert them into uric acid which is excreted out through hind gut.

Select the correct statement from the ones given below with respect to Periplaneta americana
1 There are 16 very long Malpighian tubules present at the junctions of midgut and hindgut
2 Grinding of food is carried out only by the mouth parts
3 Nervous system located dorsally, consists of segmentally arranged ganglia joined by a pair of longitudinal connective
4 Males bear a pair of short thread likes anal styles
Explanation:
Anal cerci is a appendage present in posterior segment of cockroach. Both male and female consists Anal cerci. An extra pair of accessory appendages named as anal styles is present in male cockroach which is a distinguishing character. It helps in copulation.

During copulation, cockroach transfers male gametes in the form of
1 Spermatophore
2 Sperms
3 Spermatid
4 Seminal vesicles
Explanation:
In cockroaches the sperms are stored in the seminal vesicles and are glued together in the form of bundles called spermatophores which are discharged during copulation.

Main excretory product in cockroach and other insects is
1 Uric acid
2 \(\mathrm{NH}_{3}\)
3 Urea
4 Nitrogen
Explanation:
Malpighian tubules absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut. Therefore, this insect is called uricotelic. Uric acis is the main excretory product in a cockroach and in an insect.
