Answers
Answer:
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'.
An example of a dioecious plant is Date Palm.
Explanation:
1. Dioecious are referred to those plants in which the female as well as male reproduction organs are present in different flowers.
2. The date palm plant has the male as well as female reproductive organs not in the same flower. These are present in different flowers of the plant, and hence they are considered as dioecious.
3. In such plants, one flower bears the male part and another flower contains the female part. Cross pollination may happen in such plants.
4. Self pollination is not at all possible in such kinds of plants.
5. Some other examples of dioecious plants are: Spinach, Papaya, Willow, etc.
6. The plants which are mentioned in the remaining options (cucumber, castor, maize) are monoecious. They consists male and female reproductive organs in the same flower. And hence, in these plants both types of pollination- cross and self are possible.
