Which of the following is the function of potassium?
1 1, 2 only
2 2, 3 only
3 3, 4 only
4 All of them
Explanation:
In plants, potassium is required in more abundant quantities in the meristematic tissues, buds, leaves and root tips. Potassium helps to maintain an anion-cation balance in cells and is involved in protein synthesis, opening and closing of stomata, activation of enzymes and in the maintenance of the turgidity of cells.

Which of the following are functions of Fe? a. Important constituent of cytochrome b. Activator of catalase c. Essential for chlorophyll synthesis d. Required for synthesis of ferredoxin e. A part of nitrogenase
1 a,b
2 a, b, d, e
3 a, b, c, d
4 All of them
Explanation:
Iron is required in larger amounts in comparison to other micronutrients. It is an important constituent of proteins involved in the transfer of electrons like ferredoxin and cytochromes. It activates catalase enzyme, and is essential for the formation of chlorophyll. Nitrogenase is an Mo-Fe Protein.
