Write a short note on sexuality in organisms.

(N/A) Sexuality in organisms refers to the presence of reproductive structures. Organisms can be classified based on the distribution of these structures:
$1$. Bisexual (Hermaphrodite): Organisms that possess both male and female reproductive organs in the same individual. Examples include earthworms,sponges,tapeworms,and many flowering plants.
$2$. Unisexual (Dioecious): Organisms where male and female reproductive organs are present in separate individuals. Examples include humans,cockroaches,and many higher animals.
- In fungi and plants,the term 'homothallic' or 'monoecious' is used to denote the bisexual condition,where both male and female gametes are produced by the same plant.
- The term 'heterothallic' or 'dioecious' is used to describe the unisexual condition,where male and female gametes are produced by different plants.
