Site Info, Office of Ocean Exploration and Research The proteins found in Sulfolobus are particularly important in biotechnology as they are thermostable and also can function at low pH. For example, at hydrothermal vents, vent bacteria oxidize hydrogen sulfide, add carbon dioxide and oxygen, and produce sugar, sulfur, and water: CO2 + 4H2S + O2 -> CH20 + 4S + 3H2O. Photosynthesis occurs in organelles known as chloroplasts in plants, according to the University of Illinois. 5. Anoxygenic photosynthetic bacteria are photoautotrophs (synthesize food using sunlight) that don't produce oxygen. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. The plants grow by photosynthesis and can be consumed as food, in addition to Food you also get oxygen and clothes from plants, etc. Both may occur in types of bacteria. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. 7. There is only one photosynthetic formula: CO 2 + 6H 2 O -> C 6 H 12 O 6 + 6O 2. Except for cyanobacteria, photosynthetic bacteria cannot process water. The main difference between phototrophs and chemotrophs is that phototrophs are the group of organisms that use energy from sunlight to produce ATP to bring out cellular functions whereas chemotrophs are organisms that acquire energy from chemical oxidation or the chemosynthesis. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Occurs only in some chemosynthetic bacteria. Some groups of these bacteria are well suited to conditions that would have existed on the earth billions of years ago, leading some to postulate that these are living representatives of the earliest life on earth. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight - on land, in shallow water, even inside and below clear ice. – Own work assumed (based on copyright claims) (CC BY-SA 3.0) via Commons Wikimedia. Photosynthetic prokaryotes rely on chlorophyll to make their own food through the process called photosynthesis. They contain a special structure known as heterocyst which is capable of fixing nitrogen from the atmosphere. Chemosynthetic bacteria are present in hot springs on land and on the seafloor around hydrothermal vents, whale carcasses, cold seeps and sunken ships.

On the other hand, chemosynthetic prokaryotes use the process of chemosynthesis to get energy from the oxidation of inorganic matters. In the most simple words, the Photosynthetic bacteria use sunlight energy, and Chemosynthetic bacteria use chemical energy to synthesize their food from inorganic substances like H 2 O, CO 2, H 2 S. See, the concept is that the bacteria will need to prepare its own food to get the energy for its survival. Iron bacteria - Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans are some of the bacteria that oxidize iron.This process has been shown to occur under different conditioned depending on the organism (e.g. They differ from other bacteria in that cyanobacteria possess chlorophyll-a, while most bacteria do not contain chlorophyll. Chloroplasts used to live as free bacteria, which invaded non-photosynthetic cells and eventually became embedded in plants. Summary. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight – on land, in shallow water, even inside and below clear ice. In the deep ocean, however, there is no light and thus there are no plants; so instead of sunlight being the primary form of energy, chemical energy is produced via chemosynthesis. Formed by some bacteria in unfavorable environments. To summarise, bacterial and plant photosynthetic systems differ in structure and constituents, but both are light-dependent reactions, and there occurs atmospheric CO 2 fixation. Ecosystems depend upon the ability of some organisms to convert inorganic compounds into food that other organisms can then exploit (or eat!). Gutierrez, Jose Juan. 5. So, photosynthetic bacteria require colored pigments to absorb all that light and its energy. 1. Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source. Bacteria can, however, obtain some energy from infra-red rays. 6. 2. ; They grow at a pH of 2-3 and a temperature of about 80°C. Even today, photosynthesis of algae and plants is exactly similar as photosynthesis of cyanobacteria. Moreover, some species serve as inoculants in the manufacturing process of biofertilizers. They are mainly found in freshwater environments and in damp terrestrial environments. Photosynthesis takes place on land and in shallow water where sunlight can reach seaweeds. However, in environments where there is no sunlight and thus no plants, organisms instead rely on primary production through a process called chemosynthesis, which runs on chemical energy. • Autotrophic is photosynthesis: – Plants, algae, and some bacteria are autotrophs –also known as self‐feeders. The photosynthesis is considered as the basic source of energy for most of the living organisms. Cyanobacteria also act as an integral partner in many symbiotic relationships. In short, photosynthetic bacteria utilize energy from sunlight for carbohydrate production, while chemosynthetic bacteria obtain energy from the oxidation of inorganic substances such as sulfur, hydrogen sulfide, methane, etc. Chemosynthetic and photosynthetic autotrophs are two types of autotrophs.
