Which micronutrient is required for splitting of water molecule during photosynthesis?
manganese
molybdenum
magnesium
copper
Manganese is absorbed by plants in the form of Mn2+ ions. It serves various important functions, including the activation of enzymes involved in respiration, nitrogen metabolism, and photosynthesis. However, its primary role lies in the process of photosynthesis, where it plays a crucial part in the splitting of water molecules to release oxygen.
Option 1 is the correct answer.
