Cockroach-Unisexual/Dioecious
In cockroaches, male and female reproductive organisms are present on separate individuals and hence they are considered to be unisexual or dioecious.

Frogs too have male and female sex organs in separate organisms and are hence unisexual or dioecious.

Date palm has male and female flowers on separate plants and is hence considered to be dioecious.
