Show Hint
Iron deficiency in plants can lead to chlorosis, where leaves turn yellow due to a lack of chlorophyll. This is a common nutrient deficiency in plants and can affect their growth and productivity.
Iron is an essential micronutrient required for the proper growth of plants and seeds. It is a key component of enzymes involved in processes such as photosynthesis and respiration. Iron plays a crucial role in the synthesis of chlorophyll, which is essential for photosynthesis in plants.
Thus, the correct answer is Iron.
