A dicotyledonous plant bears flowers but never produces fruits and seeds. The most probable cause for the above situation is

Answer

To solve the question regarding a dicotyledonous plant that bears flowers but never produces fruits and seeds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Flower Structure**:
- Flowers are the reproductive structures of flowering plants. They can contain male (staminate) and female (pistillate) reproductive organs.
- The ovary of a flower is crucial for fruit development, as it contains the ovules that develop into seeds after fertilization.

2. **Identifying Flower Types**:
- Flowers can be classified as either unisexual (having either male or female organs) or bisexual (having both male and female organs).
- In unisexual flowers, if a plant only has male flowers (staminate), it will not be able to produce fruits or seeds because there are no female organs present for fertilization.

3. **Dioecious vs. Monoecious Plants**:
- Dioecious plants have male and female flowers on separate plants. If a plant is dioecious and only has staminate flowers, it will not produce any fruits or seeds.
- Monoecious plants have both male and female flowers on the same plant, allowing for the possibility of fruit and seed production.

4. **Conclusion**:
- Since the question states that the dicotyledonous plant bears flowers but never produces fruits and seeds, the most probable cause is that the plant is dioecious and only bears staminate flowers. Therefore, it lacks the female reproductive structures necessary for fruit and seed development.

### Final Answer:
The most probable cause for the situation described is that the plant is dioecious and bears only staminate flowers.
