Senescence in plants leads into …..of cells

Options

A. Increase in size
B. Increase in number
C. Death
D. Differentiation.

Answer

**Step-by-Step Solution:**

1. **Understanding Senescence**: Senescence in plants refers to the process of aging, which is the final phase in the life cycle of a plant. It is characterized by a decline in metabolic activity and the eventual death of the plant.

2. **Phases of Plant Life Cycle**: The life cycle of a plant consists of three main phases:
- **Juvenile Phase**: This is the initial phase where the plant is immature and primarily focuses on vegetative growth (increasing in size and developing leaves, stems, and branches).
- **Reproductive Phase**: In this phase, the plant develops flowers, which are essential for sexual reproduction.
- **Senescence Phase**: This is the final phase where the plant undergoes aging, leading to the decline of cellular functions.

3. **Effects of Senescence**: During senescence, the plant cells undergo a process that ultimately leads to their death. This is a natural part of the plant's life cycle, as it prepares for the end of its life.

4. **Evaluating Options**: The question asks what senescence leads to in terms of cells. The options include:
- Increase in size
- Increase in number
- Death of cells
- Differentiation of cells

Since senescence is associated with aging and the decline of cellular activity, the correct answer is that senescence leads to the **death of cells**.

5. **Conclusion**: Therefore, the answer to the question "Senescence in plants leads to …..of cells" is **death of cells**.
