Find the incorrect statements about the stem system.

Options

A. Stem includes fruits, flowers and leaves
B. Stem develops from plumule of the seed
C. Growth of the stem is positive to gravity
D. Stem provides support and protection to the plant

Answer

To determine the incorrect statements about the stem system, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze Statement A: "Stem includes fruit, flowers and leaves."**
- The stem is indeed responsible for supporting leaves, flowers, and fruits. It acts as a conduit for nutrients and water between the roots and the rest of the plant.
- **Conclusion:** Statement A is correct.

2. **Analyze Statement B: "Stem developed from the plumule of the seeds."**
- The stem does develop from the plumule, which is the part of the seed embryo that will grow into the stem and leaves. The radical develops into the root, while the plumule develops into the stem.
- **Conclusion:** Statement B is correct.

3. **Analyze Statement C: "Growth of the stem is positive to the gravity."**
- This statement is incorrect. The growth of the stem is actually negative to gravity, meaning that the stem grows upwards, away from the gravitational pull, while roots grow downwards, towards gravity.
- **Conclusion:** Statement C is incorrect.

4. **Analyze Statement D: "Stem provides support and protection to the plant."**
- The stem does provide structural support to the plant and protects the internal tissues. It also plays a role in transporting nutrients and water.
- **Conclusion:** Statement D is correct.

### Final Conclusion:
The incorrect statement about the stem system is **C: "Growth of the stem is positive to the gravity."**
