Continuous growth of plants throughout the life is due to

Options

A. Meiotic divisions
B. Meiotic divisions of zygote
C. Mitotic divisions of meristems
D. Cell differntiation

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Growth**: Plants exhibit continuous growth throughout their life due to specific types of cell division. Unlike animals, plants do not have a fixed growth period and can grow indefinitely.

2. **Evaluating the Options**:
- **Option 1: Meiotic Division**: This type of division is known as reductional division, where the chromosome number is halved, resulting in the formation of gametes. It does not contribute to the continuous growth of plants. Therefore, this option is incorrect.

- **Option 2: Meiotic Division of Zygote**: This option is also incorrect. The zygote undergoes mitotic divisions to develop into an organism, not meiotic divisions. Meiotic division occurs later in the formation of gametes, not in the zygote itself.

- **Option 3: Mitotic Division of Meristems**: This is the correct option. Meristems are regions in plants where active cell division occurs. The mitotic division in these regions leads to an increase in the number of cells, contributing to the continuous growth of the plant.

- **Option 4: Cell Differentiation**: While cell differentiation is important for the development of specialized cells, it does not account for the continuous growth of plants. Thus, this option is also incorrect.

3. **Conclusion**: Based on the evaluation of the options, the correct answer is that the continuous growth of plants throughout their life is due to the **mitotic division of meristems**.

**Final Answer**: The continuous growth of plants throughout their life is due to the mitotic division of meristems.
