Dioecious plants are those in which the male and female reproductive organs are present on separate plants.
In the case of papaya, individual plants can be either male or female, and both male and female flowers are produced on separate plants.
Therefore, the correct answer for an example of a dioecious plant is (A) Papaya.
The correct answer is:
Option 1: Papaya
A dioecious plant is a plant species where individual plants have either male or female reproductive organs, but not both. In other words, male and female flowers are found on separate plants.
Papaya is a dioecious plant, meaning it has separate male and female plants. Only female plants produce fruit, while male plants produce pollen.
The other options are incorrect because:
Cucurbita (Option 2) is typically monoecious, meaning it has both male and female flowers on the same plant (e.g., pumpkins, squashes).
Coconut (Option 3) is also monoecious, with both male and female flowers on the same plant.
Mango (Option 4) is generally monoecious as well.
Thus, papaya is an example of a dioecious plant.
