Solution
Cockroach mainly excretes uric acid. Excretion of uric acid as excretory product is called as uricotelic excretion. Animals which live in dry conditions have to conserve water in their bodies. Therefore they synthesize crystals of uric acid from ammonia. Uric acid crystals are non toxic and almost insoluble in water.
