{'mineral constituent': [1, 0, 0, 0], 'chlorophyll': [5, 0, 1, 4], 'magnesium': [1, 0, 2, 3], 'calcium': [2, 0, 0, 4], 'potassium': [1, 0, 0, 2], 'iron': [0, 0, 1, 1]}
The correct answer is option 2, which is Magnesium. Chlorophyll is a pigment found in plants that is responsible for capturing sunlight during photosynthesis. It plays a crucial role in converting sunlight, carbon dioxide, and water into glucose and oxygen. The central atom in the chlorophyll molecule is magnesium, which is essential for its function. Magnesium acts as an electron donor and helps in the transfer of energy during photosynthesis. This mineral allows chlorophyll to absorb light and convert it into chemical energy. Without magnesium, plants would not be able to carry out photosynthesis effectively and would struggle to produce the energy they need for growth and survival.
