Chemistry of leaf colors

Leaves of plants are the factory units for making the food in the form of sugar from carbon dioxide, water and light by a process called photosynthesis. The process is accomplished with the help of chlorophyll which belongs to a class of organic compounds called porphyrins.

It also decays at a continuous rate irrespective… Read More »Chemistry of leaf colors
