Question

Study the table and find deficiency symptoms shown in plants

• A. A: Stunted growth, B: Chlorosis, C: Necrosis
• B. A: Chlorosis, B: Necrosis, C: Inhibition of cell division
• C. A: Delay flowering, B: Stunted growth, C: Chlorosis
• D. A: Premature leaf fall, B: Necrosis, C: Chlorosis

Hint:

In plants, deficiencies in essential nutrients like Fe, Mn, Zn lead to chlorosis, while Cu, Ca deficiencies cause necrosis. N, K deficiencies result in inhibition of cell division, leading to stunted growth.

Answer 1

The Correct Option is B

Analysis of Deficiency Symptoms and Corresponding Elements:

A: Fe, Mn, Zn → Chlorosis ✅ 🔹 Deficiency of Iron (Fe), Manganese (Mn), and Zinc (Zn) leads to chlorosis (yellowing of leaves due to lack of chlorophyll), especially in younger leaves.

B: Cu, Ca → Necrosis ✅ 🔹 A deficiency of Copper (Cu) and Calcium (Ca) results in necrosis (localized death of plant tissue), often causing dark spots or tissue decay in leaves.

C: N, K → Inhibition of Cell Division ✅ 🔹 A deficiency in Nitrogen (N) and Potassium (K) leads to inhibition of cell division, resulting in stunted growth and underdeveloped plant tissues.

✅ Correct Answer: (2) A: Chlorosis, B: Necrosis, C: Inhibition of Cell Division.
