What does Zn stand for?

Zn represents Zinc on the periodic table of elements, where each chemical element is assigned a unique symbol. Zinc is a crucial micronutrient for plants, playing essential roles in various physiological processes, including enzyme activity, protein synthesis, and regulation of growth hormones. It is vital for the synthesis of chlorophyll and plays a significant part in the plant's overall health and development.

The other options represent different elements that have distinct chemical symbols: Calcium is denoted by Ca, Magnesium by Mg, and Iron by Fe. Understanding the role of these nutrients, particularly zinc, is vital for agricultural practices and crop management, as deficiencies or imbalances can lead to significant limitations in crop yield and quality.
