NEET Botany Mineral Nutrition MCQs

A scientist is studying the role of micronutrients in plant growth. They observe that a particular plant species exhibits stunted growth and interveinal chlorosis in young leaves. Which micronutrient deficiency is MOST likely responsible for these symptoms?

Which of the following combinations correctly matches the ion, its role in plants, and a typical mechanism of its uptake?

(A) Calcium - Cell wall component - Symport with protons

(B) Potassium - Stomatal regulation - Channel proteins

(C) Nitrate - Nucleic acid synthesis - Active transport through ATPases

(D) Magnesium - Chlorophyll constituent - Passive diffusion

A patient presents with severe muscle weakness, difficulty walking, and loss of tendon reflexes. Further investigation reveals impaired glucose metabolism and cardiac abnormalities. These symptoms are MOST likely associated with a deficiency of:

A child displays stunted growth, impaired wound healing, and skin lesions. Biochemical analysis reveals decreased collagen synthesis. Which pair of nutrient deficiencies is MOST likely responsible for these symptoms?

A plant exhibits interveinal chlorosis in its young leaves, while older leaves remain relatively unaffected. This symptom is indicative of a deficiency in which micronutrient that is relatively immobile within the plant?

Which of the following deficiency symptoms is NOT correctly paired with the deficient nutrient?

(a) Necrosis of leaf tips - Calcium

(b) Heart rot in sugar beet - Boron

(c) Whiptail in cauliflower - Molybdenum

(d) Dieback of shoots - Copper

Which of the following deficiency symptoms is INCORRECTLY paired with the deficient nutrient?

A plant exhibits stunted growth, particularly in the roots, and its older leaves show chlorosis. Which nutrient is most likely deficient?

Read the functions given below and identify the concerned nutrient

I. Activator of catalase

II. Important constituent of cytochrome

III. Important constituent of proteins involved in ETS

IV. Essential for chlorophyll synthesis
