Answer 1

Answer:

Monoecious plants are those which contain male and female reproductive organs(stamens and pistil) in different unisexual flowers but on the same plant. Unisexual flowers are those which possess either male reproductive organ (stamens) and female reproductive organs (pistil).

So, the correct answer is 'If both male and female flowers are present but flowers are unisexual'.

The animal which has either the male or the female reproductive organs are known as unisexual organisms. These organisms exhibit the property of sexual dimorphism. Sexual dimorphism are the differences in appearance between males and females of the same species. The lizards are the reptiles which are bisexual. There are no different sexes but both the sexes are present in the same organism. Humans are unisexual.

Thus, the correct answer is option A.
