Stems of potato, ginger and turmeric are modified to

Options

A. Respiration
B. Perform phosynthesis
C. Store food
D. Provide support

Answer

To answer the question regarding the modifications of stems in potato, ginger, and turmeric, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Plants**: The question mentions three plants: potato, ginger, and turmeric. We need to analyze the stem modifications in each of these plants.

2. **Potato Stem Modification**: The stem of the potato is modified into a structure known as a **tuber**. Tubers are specialized storage organs that primarily store starch, which is a form of food.

3. **Ginger Stem Modification**: The stem of ginger is modified into a structure called a **rhizome**. Rhizomes are horizontal underground stems that also serve as storage organs for nutrients and energy.

4. **Turmeric Stem Modification**: Similar to ginger, the stem of turmeric is also modified into a **rhizome**. Like ginger rhizomes, turmeric rhizomes store food and nutrients.

5. **Function of Modifications**: The primary function of these modifications (tuber in potato and rhizomes in ginger and turmeric) is to **store food**. This is crucial for the plants' survival, especially during unfavorable conditions.

6. **Evaluate the Options**: The options provided are:
- Respiration
- Perform photosynthesis
- Store food
- Provide support

Based on our analysis, the correct answer is that the modified stems of potato, ginger, and turmeric are primarily for **storing food**.

### Final Answer:
The stems of potato, ginger, and turmeric are modified to **store food**.
