What elements make up of plants?

Plants are primarily composed of several key elements, including carbon, hydrogen, oxygen, nitrogen, phosphorus, and potassium. Carbon, hydrogen, and oxygen are fundamental components of carbohydrates, which are essential for energy and structure. Nitrogen is crucial for amino acids and proteins, while phosphorus and potassium play vital roles in energy transfer and overall plant health. Trace elements like magnesium, calcium, and sulfur are also important for various physiological functions.
