Which nutrient is critical for energy transfer in plants?

Phosphorus is vital for energy transfer in plants primarily because it is a key component of adenosine triphosphate (ATP), the molecule that stores and provides energy for various biochemical reactions. ATP is crucial for processes such as photosynthesis and respiration, where energy is required for the synthesis of organic compounds and the maintenance of cellular functions.

In addition to its role in energy transfer, phosphorus is also important in the formation of nucleic acids (DNA and RNA) and is involved in the activation of enzymes and other metabolic processes. Though other nutrients play roles in plant health and development, phosphorus uniquely serves as the cornerstone of energy metabolism, making it essential for overall plant growth and productivity.
