Region of elongation is present (a)____ to the region of meristem. And region of maturation is present (b)____ to thhe region of elongation.

Answer

To answer the question regarding the positions of the regions of elongation and maturation in relation to the region of meristem in a root structure, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Regions**: In a typical root structure, there are three main regions: the region of meristem, the region of elongation, and the region of maturation.

2. **Position of the Region of Meristem**: The region of meristem is located at the tip of the root. This is where active cell division occurs, allowing the root to grow.

3. **Position of the Region of Elongation**: The region of elongation is located just above the region of meristem. This region is responsible for the increase in length of the root as the cells produced in the meristematic region elongate.

4. **Position of the Region of Maturation**: The region of maturation is found above the region of elongation. This region is where the cells differentiate and mature, and it contains root hairs that help in the absorption of water and nutrients.

5. **Fill in the Blanks**:
- For the first blank (a), we can conclude that the region of elongation is present **above** the region of meristem.
- For the second blank (b), we can conclude that the region of maturation is present **above** the region of elongation.

### Final Answer:
Region of elongation is present (a) **above** to the region of meristem. And region of maturation is present (b) **above** to the region of elongation.
