Regions of root system from root base to tip sequence is -

Options

A. Maturation zone - Cell division zone - Elongation zone
B. Maturation zone - Elongation zone - Meristmatic activity
C. Cell division zone - Elongation zone - Maturation zone
D. None of these

Answer

To answer the question regarding the sequence of regions in the root system from the root base to the tip, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Regions of the Root System**: The root system consists of three main regions that can be identified based on their functions and characteristics.

2. **Region of Maturation**: This is the first region when moving from the root base towards the tip. In this region, the cells differentiate and mature into various types of root cells. It is responsible for the absorption of water and nutrients.

3. **Region of Elongation**: Following the region of maturation, the next region is the elongation zone. In this area, the cells increase in length, which contributes to the growth of the root. This is where the root begins to extend deeper into the soil.

4. **Meristematic Region**: Finally, at the tip of the root, we have the meristematic region. This region contains actively dividing cells that are responsible for the growth of the root. These cells are undifferentiated and will eventually differentiate into various cell types.

5. **Sequence from Base to Tip**: Therefore, the correct sequence of the regions from the root base to the tip is:
- Region of Maturation
- Region of Elongation
- Meristematic Region

### Final Answer:
The correct sequence of the regions of the root system from the root base to the tip is:
1. Region of Maturation
2. Region of Elongation
3. Meristematic Region
