Requirements of photosynthesis are

Options

A. air
B. water
C. sunlight
D. All of these

Explanation

To answer the question "What are the requirements of photosynthesis?", let's break down the requirements step by step.

### Step 1: Identify the main components needed for photosynthesis
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. The main components required for this process are:

1. **Sunlight**: This is the energy source that drives the photosynthesis process.
2. **Water (H2O)**: This is absorbed by the roots of the plants and is essential for the photosynthesis process.
3. **Carbon Dioxide (CO2)**: This gas is taken in from the atmosphere through small openings in the leaves called stomata.

### Step 2: Understand the role of chlorophyll
Chlorophyll is a green pigment found in the chloroplasts of plant cells. It plays a crucial role in photosynthesis by capturing sunlight. Without chlorophyll, plants would not be able to absorb sunlight effectively, which is essential for converting carbon dioxide and water into glucose and oxygen.

### Step 3: Summarize the requirements
From the above points, we can summarize that the requirements for photosynthesis are:
- **Sunlight**
- **Water**
- **Carbon Dioxide (from air)**
- **Chlorophyll**

### Step 4: Conclusion
Therefore, the correct answer to the question regarding the requirements of photosynthesis is:
**Option D: All of these (Air, Water, and Sunlight)**.
