Which of these parts of the Makoi plant is incorrectly described ?

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 determine which part of the Makoi plant (Solanum nigrum) is incorrectly described, we will analyze each description step by step.

### Step 1: Analyze the Leaves
- **Description**: The leaves are alternate, simple, extipulate, with reticular venation.
- **Analysis**:
- **Alternate**: Leaves are arranged alternately on the stem, which is correct.
- **Simple**: The leaves are not divided into smaller leaflets, which is also correct.
- **Extipulate**: This means there are no stipules present at the base of the leaf, which is correct for this plant.
- **Reticular Venation**: The leaves have a network of veins, which is typical for the Solanaceae family.
- **Conclusion**: This description is correct.

### Step 2: Analyze the Corolla (Petals)
- **Description**: Petals are 5, and they exhibit gamma-syphilis with valvate estivation.
- **Analysis**:
- **Petals 5**: The flower has five petals, which is accurate.
- **Gamma-syphilis**: This indicates that the petals are fused at the base, which is correct.
- **Valvate Estivation**: The petals touch each other at the edges, which is also characteristic of the Solanaceae family.
- **Conclusion**: This description is correct.

### Step 3: Analyze the Gynaeceum
- **Description**: The ovary is syncarpous with two carpels, bilocular, and superior.
- **Analysis**:
- **Syncarpous**: The carpels are fused, which is correct.
- **Two Carpels**: This is accurate for the Makoi plant.
- **Bilocular**: The ovary has two chambers, which is correct.
- **Superior Ovary**: The ovary is positioned above the other floral parts, which is also correct.
- **Conclusion**: This description is correct.

### Step 4: Analyze the Seeds
- **Description**: Many seeds are said to be of fruit without endosperm.
- **Analysis**:
- **Many Seeds**: This is misleading; the Makoi plant typically has a few seeds.
- **Without Endosperm**: This is incorrect as the seeds of Solanum nigrum do contain endosperm, specifically cellular endosperm.
- **Conclusion**: This description is incorrect.

### Final Conclusion
The part of the Makoi plant that is incorrectly described is the seeds, as they do not have many seeds and they do contain endosperm.
