HOTS Questions Chapter 12 Mineral Nutrition Class 11 Biology with Answers
Q1. It is observed that deficiency of a particular element showed its symptoms initially in older leaves and than younger leaves.
• Does it indicate that the element is actively mobilized or relatively immobile?
• Name two elements which are highly mobile and two which are relatively immobile.
• How is the aspect of mobility of elements important to horticulture and agriculture?
Ans.1 A) This is actively mobilized.
B) Highly mobile elements: Nitrogen and magnesium. Relatively immobile: Calcium and Boron.
C) The symptoms of deficiency of mobile elements are more pronounced in the older leaves and symptoms of deficiency of relatively immobile elements appear first in younger leaves. So this information can be utilized in horticulture as well as agriculture to get a broad idea of deficiency
elements in plants.
Q2. How are plants grown in glass containers to judge essential elements?
Ans.2 In the solution culture the plants are grown in pure nutrient media with only required elements. The glass containers are covered with black paper to protect roots from direct light. In other glass containers plant is allowed to grow artificially with same nutritive culture that contains all essential elements except one and its essentiality is to be judged. They are compared with the control plant grown in balanced nutrient medium. When there is any change in morphological features compared with normal plant this may be due to deficiency of specific element.
