Select the correct option with respect to cockroaches
1 Malphigian tubules convert nitrogenous wastes into urea
2 Males bear short anal styles not present in females
3 Nervous system comprises of a dorsal nerve cord and ten pairs of ganglia
4 The forewings are tegmina which are used to flight
Explanation:
Malpighian tubules are the main excretory organ in cockroach. They extract nitrogenous wastes and water from haemolymph and reabsorb certain salts resulting in precipitation of uric acid. So cockroach is uricotelic. Males have paired anal styles on \(9^{\text {th }}\) abdominal stermine which are absent in females.

In the digestive system of cockroach, gastric caeca is present at the junction of
1 Midgut and hindgut
2 Hindgut and foregut
3 Foregut and proventriculus
4 Foregut and midgut
Explanation:
In the digestive system of a cockroach, a ring of 6-8 blind tubules called gastric caeca is present at the junction of foregut and midgut, which secrete digestive juices, to aid digestive of food.

Mark the incorrect one w.r.t reproductive system of male cockroach
1 A characteristic mushroom shaped gland is present in \(6^{\text {th }}-7^{\text {th }}\) abdominal segments which function as an accessory reproductive gland
2 A pair of testes lying one on each lateral side in \(4^{\text {th }}-6^{\text {th }}\) abdominal segment
3 Sperms are stored in seminal vesicles
4 The ejaculatory duct opens into male gonopore situated dorsal to anus
Explanation:
The ejaculatory duct in a male cockroach opens out through the male gonopore that lies ventral to the anus.

Phallic gland is found in
1 Male cockroach
2 Female cockroach
3 Rat
4 Leech
Explanation:
Conglobate gland is also called as Phallic gland, it is present beneath utricular gland in \({{\rm{6}}^{{\rm{th}}}}\) segment,opens outside by a pore close to the gonopore. Conglobate gland is large, elongated sac like structure lies beneath mushroom gland and ejaculatory duct. Secretion of conglobate gland forms outer layer of spermatophores.
