#4. Which of the following elements is responsible for maintaining turgor in cells?

#5. Which is essential for the growth of root tip?

Calcium is required by dividing and differentiating cells.

#6. In which of the following all three are macronutrients?

#7. During biological nitrogen fixation, inactivation of nitrogenase by oxygen poisoning is prevented by :

#8. Minerals known to be required in large amounts for plant growth include

Macronutrients are required in large amounts for plant growth.

#9. Deficiency symptoms of nitrogen and potassium are visible first in

#11. Which one of the following is wrong statement?

Phosphorus is not constituent of all proteins.

#12. Which one of the following is correctly matched ?

#13. For its action, nitrogenase requires
