Question

An example of a dioecious plant is

• A. Cucumber
• B. Maize
• C. Castor bean
• D. Date palm

Answer 1

Answer: (D)

Date palm

A dioecious plant is one where the male and female reproductive systems occur on separate plants. While both plants produce flowers, one plant has the male reproductive parts and the other plant has the female parts. A dioecious plant requires two separate plants (a male and a female) to successfully pollinate, and only the female plant bears the fruit. Date palm is dioecious because these plants bear exclusively either male flowers or female flowers.

So the correct option is 'date palm'.
