Magnesium Deficiency Causes Chlorosis and Stunted Growth

Steps:

• Magnesium is a key component of chlorophyll, essential for photosynthesis.
• Without enough magnesium, chlorophyll production decreases, leading to yellow leaves (chlorosis).
• Reduced photosynthesis impairs energy production, causing stunted growth.
• Option C matches these symptoms: stunted growth and yellow leaves.

Why C is correct:

• Magnesium ions form the core of chlorophyll molecules; deficiency disrupts photosynthesis, resulting in yellow leaves and stunted growth per plant nutrition principles.

Why the others are wrong:

• A: Elongated stems indicate nitrogen deficiency, not magnesium.
• B: Green leaves contradict chlorosis from magnesium shortage.
• D: Elongated stems and green leaves do not align with magnesium's role in chlorophyll.

Final answer: C
