Q5
Medium
A deficiency of which mineral leads to the condition known as 'mosaic disease' in plants?
A.
Nitrogen
B.
Potassium
C.
Magnesium
D.
Iron
Show Answer & Explanation
Correct Answer: D

Q7
Medium
If a plant is showing stunted growth and necrosis at the tips of young leaves, which mineral deficiency might you suspect?
A.
Magnesium
B.
Potassium
C.
Nitrogen
D.
Calcium
Show Answer & Explanation
Correct Answer: D
Calcium is critical for cell division and growth; its deficiency results in stunted growth and necrosis, especially in new leaves.
Q8
Hard
Which essential mineral is primarily involved in the synthesis of chlorophyll and is often deficient in soils, leading to reduced photosynthesis in plants?
A.
Iron
B.
Magnesium
C.
Zinc
D.
Manganese
Show Answer & Explanation
Correct Answer: B
Magnesium is a crucial component of chlorophyll, the green pigment in plants. A deficiency in magnesium can lead to poor chlorophyll production, thereby reducing photosynthesis and overall plant health.
Q9
Hard
A study reveals that a certain plant exhibits stunted growth due to a deficiency in an essential micronutrient that plays a vital role in enzyme activation and protein synthesis. Which micronutrient is likely deficient?
A.
Copper
B.
Boron
C.
Molybdenum
D.
Iron
Show Answer & Explanation
Correct Answer: A
Copper is an essential micronutrient that is crucial for enzyme activation and protein synthesis in plants. A deficiency in copper can severely affect growth and development, leading to stunted growth.
Q10
Hard
Which of the following minerals is primarily responsible for the synthesis of chlorophyll in plants?
A.
Magnesium
B.
Iron
C.
Copper
D.
Manganese
Show Answer & Explanation
Correct Answer: A
Magnesium is an essential component of chlorophyll, the pigment crucial for photosynthesis, allowing plants to capture light energy.
