Plants make their own food in the presence of

Options

A. sunlight and chlorophyll
B. water
C. `CO_(2)`
D. all of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Plants have a unique ability to make their own food through a process called photosynthesis. This process is essential for their growth and survival.

2. **Key Components of Photosynthesis**: The main components required for photosynthesis are:
- **Sunlight**: This is the primary energy source that drives the process.
- **Chlorophyll**: This is a green pigment found in plants that captures sunlight.
- **Water (H2O)**: Plants absorb water from the soil, which is necessary for photosynthesis.
- **Carbon Dioxide (CO2)**: Plants take in carbon dioxide from the air through small openings in their leaves called stomata.

3. **The Process**: During photosynthesis, chlorophyll absorbs sunlight and uses its energy to convert water and carbon dioxide into glucose (a type of sugar) and oxygen. The overall equation for photosynthesis can be summarized as:
\[ \text{6 CO}_2 + \text{6 H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + \text{6 O}_2 \]
This means that six molecules of carbon dioxide and six molecules of water, using light energy, produce one molecule of glucose and six molecules of oxygen.

4. **Conclusion**: Therefore, plants make their own food in the presence of sunlight, chlorophyll, water, and carbon dioxide. All these components work together to facilitate the process of photosynthesis.

5. **Final Answer**: The answer to the question is that plants make their own food in the presence of sunlight, chlorophyll, water, and carbon dioxide.
