Question

Unisexual flowers are present on the same plant in

• A. Date palm
• B. Papaya
• C. Coconut
• D. Commelina

Answer 1

The correct option is C

Coconut

When each flower has functional male and female parts the flower is said to be perfect. An imperfect flower, then, is one that has either functional male parts (staminate flowers), or functional female parts (pistillate or carpellate flowers), but not both. When a plant has imperfect flowers, they can be arranged in one of two ways.
If separate staminate and carpellate flowers are always found on the same plant, the species is called monoecious. If separate staminate and carpellate flowers are always found on different plants, the species is called dioecious.

• Papaya is a dioecious plant, having male and female flowers on separate plants.
• The date palm is dioecious, having separate male and female plants.
• Commelina is a genus of approximately 170 species commonly called dayflowers. The flowers are either bisexual or male.
• The coconut flowers develop inside a large green bud which is called ‘The Spathe’ which keep both male and female flowers. Hence, coconut is a monoecious plant.
