All cell of a plant are descendents of the zygote.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that all cells of a plant are descendants of the zygote. We need to determine if this is true or false.

2. **Defining Key Terms**:
- **Descendants**: In this context, it means that all cells in the plant originate from the zygote.
- **Zygote**: This is the fertilized egg that forms when the male and female gametes fuse during fertilization.

3. **Process of Fertilization**:
- Fertilization occurs when the male gamete (sperm) and the female gamete (egg) unite.
- This fusion results in the formation of a zygote.

4. **Development from Zygote**:
- After fertilization, the zygote undergoes a series of cell divisions.
- These divisions are precise and ordered, leading to the development of the embryo.

5. **Formation of Plant Structures**:
- The embryo formed from the zygote will eventually differentiate into various parts of the plant, including roots, stems, leaves, and flowers.
- All these cells are derived from the original zygote through continuous cell division and differentiation.

6. **Conclusion**: Since all cells of the plant originate from the zygote through this process of division and differentiation, the statement is true.

**Final Answer**: The statement "All cells of a plant are descendants of the zygote" is **True**.
