Question

Which of the following is true in case of Periplaneta americana?

• A. They are diurnal
• B. They are carnivores
• C. They are hermaphrodites
• D. Their body is segmented

Answer 1

The correct option is D Their body is segmented

Cockroaches feed on all kinds of matter including food, paper, plastic, wires, cloth and even the dead bodies of fellow cockroaches (cannibalism). Hence they are omnivores.
They are active at night and rest during the day. Hence they are nocturnal creatures.
Male and female sex organs are present in different individuals. Hence they are not hermaphrodites but unisexual organisms.
Their body is divided into three regions – head, thorax and abdomen. Head is made up of six fused segments, thorax is made up of three segments and abdomen consists of ten segments.
