What nutrient is essential for the production of a plant's survival?

• A. Zinc
• B. Iron
• C. Manganese
• D. Calcium

Answer: (C)

The essential nutrient for a plant's survival among the options provided is calcium. Calcium plays several important roles in the growth and health of plants. It is a vital component of cell walls, contributing to their structural integrity by forming calcium pectate, which is crucial for maintaining the integrity and stability of cells as they grow and expand. Additionally, calcium acts as a secondary messenger in various signaling pathways, helping the plant respond to environmental stimuli and regulate processes such as nutrient uptake and cell division. While zinc, iron, and manganese are also important micronutrients that contribute to various biochemical processes, such as enzyme function and photosynthesis, calcium is particularly crucial for structural support and communication within the plant. Without adequate calcium, plants can suffer from issues like blossom end rot in tomatoes or tip burn in lettuce, illustrating the nutrient's critical role in plant health and survival.
