Crabohydrates, the most abundant biomlecles on earth, are
produced by

Options

A. All bacteria , fungi and algae
B. Fungi, algae, and green plant cells
C. Some bacteria , algae, and green plants cells
D. Viruses, fungi and bacteria

Answer

**Step-by-Step Text Solution:**

1. **Understanding Carbohydrates**: Carbohydrates are the most abundant biomolecules on Earth. They include various forms such as cellulose, starch, glycogen, glucose, and fructose.

2. **Photosynthesis Process**: Carbohydrates are produced through the process of photosynthesis. During photosynthesis, carbon dioxide from the atmosphere combines with water in the presence of sunlight and chlorophyll (the green pigment in plants) to form glucose. Oxygen is released as a by-product.

3. **Photosynthetic Organisms**: The primary organisms that perform photosynthesis include:
- Green plants
- Some types of algae
- Some bacteria (though not all bacteria are photosynthetic)

4. **Evaluating the Options**:
- **Option A**: All bacteria, fungi, and algae. (Incorrect: Fungi are not photosynthetic.)
- **Option B**: Fungi, algae, and green plant cells. (Incorrect: Fungi are not photosynthetic.)
- **Option C**: Some bacteria, algae, and green plant cells. (Correct: All these organisms can perform photosynthesis.)
- **Option D**: Viruses, fungi, and bacteria. (Incorrect: Viruses and fungi are not photosynthetic.)

5. **Conclusion**: The correct answer is **Option C**: Some bacteria, algae, and green plant cells are responsible for the production of carbohydrates through photosynthesis.
