1. What are the different Methods to Study Mineral requirements in Plants?
The different methods to study mineral requirements in plants are as follows:
Aeroponics:
In this technique od studying mineral requirements, minerals are sprayed suspended in the air.
Hydroponics:
In this technique, plants are grown in a nutrient solution instead of soil. This technique is employed for the commercial production of vegetable. Moreover, this technique also comes in handy for studying mineral deficiency diseases in plants.
2. What are the Criteria for the Essentiality of an Element in Plants?
The various criteria for the essentiality of an element in plants include:
The element must be necessary for the process of growth and reproduction in the plant. The plant is unable to complete its life cycle without the element.
The element must have a specific requirement in the plant and should not be replaceable by any other element.
The element must be directly involved in the metabolism of the plant.
On the basis of the essentiality criteria, elements in plants are classified as Macronutrients, those required in larger amounts and Micronutrients, those required in comparatively lesser amounts.
3. How are essential Elements Categorised?
Essential elements are categorised into different groups on the basis of their functions. These include:
Structural Elements of Cells: These include elements such as carbon, hydrogen, nitrogen and oxygen that serve as components of various biomolecules such as lipids, amino acids, etc.
Elements for Energy and Metabolism: These include magnesium ion in chlorophyll and phosphorus ion in ATP.
Influencers of Enzyme Action: These include essential elements that act activators or inhibitors of certain enzymes. Example. Mg2+t that activates ribulose biphosphate carboxylase oxygenase and phosphoenolpyruvate carboxylase, both required in carbon fixation.
Regulating Osmolarity: Elements like phosphorus that regulate the opening and closing of the stomata by maintaining the osmolarity.

The Chapter also provides various model answers related to the topic.
9. What are beneficial and toxic elements? Explain with examples, according to Chapter 12 of Class 11 Biology.
Beneficial elements, just like the name suggests, are beneficial or favourable for the growth of the plants such as silicon, sodium, and cobalt. They are not essential but can promote their growth. Toxic elements, on the other hand, are the nutrients that plants in small quantities require. If they are not provided to the plants, they become deficient in these nutrients, and it causes diseases in the plants. Some examples are potassium, sodium, and magnesium.
