Photosynthesis reaction involves two reactants, carbon dioxide and water. These two reactants yield two products, namely, oxygen and glucose. Hence, the photosynthesis reaction is considered to be an endothermic reaction. Following is the photosynthesis formula:
| 6CO2 + 6H2O —> C6H12O6 + 6O2 |
Unlike plants, certain bacteria that perform photosynthesis do not produce oxygen as the by-product of photosynthesis. Such bacteria are called anoxygenic photosynthetic bacteria. The bacteria that do produce oxygen as a by-product of photosynthesis are called oxygenic photosynthetic bacteria.
| Photosynthetic PigmentsThere are four different types of pigments present in leaves:Chlorophyll aChlorophyll bXanthophyllsCarotenoids |
Structure Of Chlorophyll
The structure of Chlorophyll consists of 4 nitrogen atoms that surround a magnesium atom. A hydrocarbon tail is also present. Pictured above is chlorophyll-f, which is more effective in near-infrared light than chlorophyll-a
Chlorophyll is a green pigment found in the chloroplasts of the plant cell and in the mesosome of cyanobacteria. This green color pigment plays a vital role in the process of photosynthesis by permitting plants to absorb energy from sunlight. Chlorophyll is a mixture of chlorophyll-a and chlorophyll-b.Besides green plants, other organisms that perform photosynthesis contain various other forms of chlorophyll such as chlorophyll-c1, chlorophyll-c2, chlorophyll-d and chlorophyll
