Photosynthesis (photo = light and synthesis = to make) is the process plants use to change carbon dioxide and water into sugar using sunlight. This sugar, glucose, is their food, and the process gives off oxygen. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water. The energy source is sunlight, and the end-products include glucose and oxygen. It is arguably the most important biochemical pathway, since nearly all life depends on it. It is a complex process occurring in higher plants, phytoplankton, algae, as well as bacteria such as cyanobacteria. Photosynthetic organisms are also referred to as autotrophs.
Leaf's green colour comes from chlorophyll. a light absorbing pigmnet in the choloroplasts that plays a central role in converting solar energy to chemical energy.
Chloroplasts are concentrated in the cells of the mesophyll, the green tissue in the interior of the leaf. CO2 enters the leaf, and O2 exits by way of tiney pores called stomata.
Water absorbed by the roots is deliveredto the leaves in veins. Leafs also use vens to export sugar to roots and other parts of the plant.
