Question

which or the following plants is dioiceous?​

Answer 1

Explanation:

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'.

Answer 2

Answer:

Dioecious plants are the unisexual plants which bear either male or female flowers, e.g., papaya, date palm etc. These plants prevent self pollination and encourage cross pollination.
