Describe the role that macro and micro nutrients play in the growth and development of plants. Describe the deficiency symptoms of various elements in plants.

Macronutrients and micronutrients are essential for the growth and development of plants, playing vital roles in physiological and metabolic processes. Macronutrients are required in large quantities, while micronutrients are needed in trace amounts. Both categories are critical for plant health, as deficiencies in any element can severely impair growth and productivity.

### Macronutrients:
1. Nitrogen (N): Nitrogen is a key component of amino acids, nucleic acids, and chlorophyll. It promotes vegetative growth and is crucial for protein synthesis. Nitrogen deficiency results in chlorosis (yellowing of leaves), stunted growth, and reduced leaf size, primarily affecting older leaves first.
