 (d) Importance of light to plants

The ultimate source of energy for plants is sunlight. Plants are autotrophic organisms, which need light in order to perform the process of photosynthesis. Plants need the sun because sunlight is made up of electromagnetic radiations which are given off as energy to the plants. These electromagnetic radiation acts as the key factor in a process that is called photosynthesis. The photons of light energy are received by the chlorophyll molecules and they give off energy in the form of electrons. These electrons are than through a cyclic as well as non-cyclic flow are converted into chemical energy i.e. ATP and NADPH in the process of photosynthesis by which organic substances are formed in plants. Thus, light is a very important factor for plants and for the survival of all the components of Earth.
