Mineral constituent of chlorophyll is - (1) Iron (2) Magnesium (3) Calcium (4) Potassium

1 Answer

Answer :

(2) Magnesium Explanation: Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also. Chlorophyll is the molecule that traps this `most elusive of all powers' - and is called a photoreceptor. It is found in the chloroplasts of green plants, and is what makes green plants, green.
