Solution
The correct option is C Ca Plants require seventeen essential mineral elements for normal growth and development. For example calcium is an essential macronutrient. Calcium (Ca) is essential for tissue differentiation (meristematic and differentiating tissues) and cell wall synthesis. It is present in cell wall as calcium pectate and forms middle lamella. Calcium is also required for normal process of cell division. It is required for spindle formation, which is important for movement of chromosomes, during mitosis.
