Options

A. Leaves : alternate , simple , exstipulate with reticulate venation
B. Corolla: petals five , gamopetallous with valvate aestivation
C. Gynoecium: bicarpellary , syncarpous with bilocular , superior ovary superior
D. Seeds : many seeds in a fruit , without endosperm

Answer

To solve the question about the incorrectly described part of the Makoi plant, we will analyze each option based on the characteristics of the Solanaceae family.

### Step-by-Step Solution:

1. **Identify the Family**: The Makoi plant belongs to the Solanaceae family. Understanding the general characteristics of this family is crucial.

2. **Examine the Leaves**:
- The leaves of the Solanaceae family are described as:
- Alternate in arrangement
- Simple (no leaflets)
- Ex-stipulate (absence of stipules)
- Reticulate venation (having a network-like pattern)
- This description is correct.

3. **Examine the Corolla**:
- The corolla (petals) of the Solanaceae family is characterized by:
- Typically 5 petals
- Gamopetalous (petals are fused together)
- Velvet aestivation (margins of petals are connected side by side)
- This description is also correct.

4. **Examine the Gynoecium**:
- The gynoecium in the Solanaceae family is characterized by:
- Bicarpillary (two carpels)
- Syncarpous (carpels are fused)
- Bilocular (two locules)
- Superior ovary (ovary is above the other floral parts)
- This description is correct as well.

5. **Examine the Seeds in the Fruit**:
- The statement regarding seeds is:
- "Many seeds in the fruit without endosperm."
- This statement is incorrect because:
- The fruits of the Solanaceae family typically contain few seeds or sometimes a single seed, and they do have cellular endosperm.

6. **Conclusion**:
- Based on the analysis, the incorrect description is found in the statement regarding the seeds. Therefore, the answer is option **d**: "Many seeds in the fruit without endosperm."

### Final Answer:
**Option d is the incorrectly described part of the Makoi plant.**
