Essential macro elements are

Options

A. Absorbed from soil
B. Manufactured during photosynthesis
C. Produced by enzymes
D. Produced by growth hormones

Explanation

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

1. **Understanding Essential Macro Elements**: Essential macro elements are nutrients that plants require in larger quantities for their growth and development. These elements are crucial for various metabolic processes within the plant.

2. **Source of Macro Elements**: These macro elements are primarily absorbed from the soil. Plants take up these nutrients through their roots, which are then utilized for various physiological functions.

3. **Role in Plant Metabolism**: The macro elements play significant roles in metabolic reactions, including photosynthesis, respiration, and the synthesis of important biomolecules. They are vital for the overall health and development of the plant.

4. **Identifying the Correct Option**: Given the options provided:
- A) Absorbed from soil
- B) Manufactured from soil
- C) Produced by enzymes
- D) Produced by growth hormones

The correct answer is A) Absorbed from soil, as macro elements are indeed taken up by plants from the soil.

5. **Conclusion**: Essential macro elements are absorbed from the soil, which is crucial for the plant's growth and metabolic functions.
