Which process causes leaf discoloration as nitrogen decreases in plants?

💡 Explanation

When nitrogen becomes scarce, protein catabolism degrades chlorophyll complexes leading to visible chlorosis (yellowing); therefore, nitrogen deficiency always causes leaf discoloration driven by protein degradation rather than increased photosynthesis or nitrogen retention because chlorosis dominates.
