The type of roots present in mustard plant is

Options

A. Fibrous roots
B. Adventitious roots
C. Tap roots
D. Nodulated roots

Answer

To determine the type of roots present in the mustard plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Root Types**: Familiarize yourself with the different types of roots. The main types include:
- **Fibrous Roots**: These roots are thin and spread out in a dense network. They typically arise from the base of the stem and are characteristic of monocots.
- **Adventitious Roots**: These roots originate from parts of the plant other than the radical (the embryonic root). They can arise from stems or leaves.
- **Tap Roots**: These roots consist of a main central root that grows deeper into the soil, with smaller lateral roots branching off. They are typical of dicots.
- **Modulated Roots**: These are specialized roots found in some legumes, which have nodules for nitrogen fixation.

2. **Identify the Plant Family**: Recognize that the mustard plant belongs to the **Brassicaceae** family, which is known for having tap roots.

3. **Evaluate the Options**:
- **Fibrous Roots**: Incorrect, as these are typical of monocots.
- **Adventitious Roots**: Incorrect, as these do not arise from the radical.
- **Tap Roots**: Correct, as mustard plants have a main root system that is characteristic of dicots.
- **Modulated Roots**: Incorrect, as these are specific to legumes.

4. **Conclusion**: Based on the analysis of the root types and the characteristics of the mustard plant, the type of roots present in the mustard plant is **tap roots**.

### Final Answer:
The type of roots present in the mustard plant is **tap roots**.
