Step-by-step solution
Calcium is required by the meristematic and differentiating tissues for cell wall formation as it is an important component of middle lamella as calcium pectate. It is also needed during for synthesis of the mitotic spindle. Necrosis refers to the death of tissues resulting in the deficiency of elements like calcium, magnesium, copper, potassium. Delayed flowering results in the deficiency of elements like nitrogen, sulfur and molybdenum. Molybdenum is a component of various enzymes like nitrogenase and nitrate red
