Difference between Photosynthetic bacteria and Chemosynthetic bacteria are in tabular form below –
No. |
Photosynthetic bacteria |
Chemosynthetic bacteria |
Definition |
||
1. | The bacteria in which photosynthesis process takes place to produce food for themselves is called as Photosynthetic bacteria. | The bacteria in which chemosynthesis takes place to produce food for themselves is called as Chemosynthetic bacteria. |
Process |
||
2. | Photosynthesis process mainly occurs in the photosynthetic bacteria. | Chemosynthesis process mainly occurs in the photosynthetic bacteria. |
Sunlight |
||
3. | Photosynthetic bacteria needs sunlight as they do photosynthesis. | Chemosynthetic bacteria do not require sunlight as they don’t perform photosynthesis. |
Source of energy |
||
4. | Solar energy or sunlight is required as a source of energy to the photosynthetic bacteria. | Substances like sulphur, methane, iron, and hydrogen gas and hydrogen sulphide are required as a source of energy to the chemosynthetic bacteria. |
Nitrogen fixation |
||
5. | Photosynthetic bacteria can fix nitrogen. | Chemosynthetic bacteria can’t fix nitrogen. |
Examples |
||
6. | Examples of photosynthetic bacteria are Nostoc, Anbaena, oscillatoria etc. | Examples of chemosynthetic bacteria are methanogenic archaea, iron and sulphur-oxidizing bacteria. |
