Apart from carbon dioxide and water, name four other raw materials which are needed by the plants.

The four other raw materials which are needed by the plants are Nitrogen, Phosphorous, Iron and Magnesium. These are the other vital nutrients required for the plant’s growth and stability. These help in the formation of new cells which further leads to the development of plant tissue. Nitrogen is the major component of amino acid and is also building blocks of protein. Phosphorus helps in the conversion of light energy into chemical energy. Iron is involved in the synthesis of chlorophyll and also for the maintenance of chloroplast structure and function. Magnesium is the central atom of chlorophyll molecule and is a building block of the green pigment in plants.
