Identify the set comprising plants that produce bisexual flowers :

  • A.Cucumber, Papaya, Rose
  • B.Mustard, Rose, Petunia
  • C.Corn, Cucumber, Petunia
  • D.Corn, Papaya, Mustard

Answer: B

All three plants produce bisexual flowers in Mustard, Rose, Petunia.

A bisexual flower has both stamens and pistil. Mustard, rose and petunia, like hibiscus, have such flowers, which is why they are the standard textbook examples of bisexual flowers.

Each other set includes a plant with unisexual flowers: cucumber has separate male and female flowers on the same plant, papaya usually bears male and female flowers on separate plants, and maize (corn) has a male tassel and female ears.
