Nudulated roots make the plant rich in

Options

A. Food
B. Proteins
C. Carbohydrates
D. Fats.

Answer

### Step-by-Step Solution:

1. **Understanding Nodulated Roots**: Nodulated roots are specialized roots that contain nodules. These nodules are often associated with certain plants, particularly leguminous plants.

2. **Function of Nodules**: The primary function of these nodules is to facilitate nitrogen fixation. This process involves converting atmospheric nitrogen into ammonia, which is a form that plants can utilize.

3. **Role of Rhizobium Bacteria**: The nodules are formed through a symbiotic relationship with Rhizobium bacteria. These bacteria live in the nodules and are responsible for the nitrogen fixation process.

4. **Importance of Nitrogen Fixation**: The ammonia produced through nitrogen fixation is crucial for the synthesis of amino acids, which are the building blocks of proteins. Therefore, nodulated roots contribute significantly to the protein content of the plant.

5. **Analyzing the Options**: Given the options:
- a) Food
- b) Proteins
- c) Carbohydrates
- d) Fats

Since nodulated roots enhance the plant's ability to produce proteins through nitrogen fixation, the correct answer is **b) Proteins**.

### Final Answer:
Nodulated roots make the plant rich in **Proteins**.
