Which of the following nutrient element is a macro-nutrient?
Answer Details
Phosphorus is a macro-nutrient. Macro-nutrients are essential elements required by plants in large quantities for healthy growth and development. These nutrients include nitrogen, phosphorus, and potassium (NPK). Phosphorus plays a crucial role in plant growth, energy transfer, and photosynthesis. It is essential for root development, flowering, and seed formation. Phosphorus is also involved in the synthesis of DNA, which is the genetic material in cells. Since phosphorus is required in large amounts by plants, it is considered a macro-nutrient.
