The first photosynthetic bacteria are believed to have emerged around 3.5 billion years ago. These early microorganisms, such as purple and green sulfur bacteria, utilized light energy to convert carbon compounds into organic matter, significantly influencing Earth's atmosphere and paving the way for the development of more complex life forms. Their photosynthetic processes contributed to the gradual increase of oxygen in the atmosphere during the Great Oxidation Event, which occurred around 2.4 billion years ago.
What else can I help you with?
Do plants photosynthesize or cellular respirate?
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
What is the era's for the first photosynthetic bacteria form dome-shaped structures called stromatolites?
The first photosynthetic bacteria to form dome-shaped structures called stromatolites lived during the Archean and Proterozoic eons, around 3.5 billion years ago. Stromatolites are some of the earliest evidence of life on Earth, showcasing the presence and activity of photosynthetic organisms in ancient aquatic environments.
What do the first cells resemble according to what scientists think?
Animal cells are Eukaryota, so they are not the first examples of cells. Archaebacteria, though they are possibly more closely related to eukaryote than bacteria are, do possess more of the hypothesis ancient methods of energy production (like thermoautotrophism and chemotherapeutic) which were prevalent before photosynthesis and aerobic respiration. Mitochondria are related to bacteria (specifically purple photosynthetic bacteria), and they perform aerobic respiration. Aerobic respiration cannot have been the original method for deriving energy, as it required oxygen - which was not abundant in the atmosphere until photosynthesis evolved. Chloroplasts are also related to bacteria (cyanobacteria) and they perform photosynthesis. It is currently believed that photosynthesis was not one of the original methods for deriving energy. So my answer would be archaebacteria.
What three cell structures that are needed for photosynthesis?
Chloroplasts, thylakoids, and chlorophyll are three cell structures needed for photosynthesis. Chloroplasts are the organelles where photosynthesis occurs, thylakoids are structures within the chloroplasts where light reactions take place, and chlorophyll is the pigment that absorbs light energy for photosynthesis.
Were the first organisms that released oxygen as a by-product of photosynthesis?
No, they were not Toxic was actually poinsonous to the Anaerobic photoautotrophs. However cyanobacteria (a.k.a pondscum) is believed to be the first bacteria to give off oxygen as a by-product of photosynthetic processes.
Is the production of hydrogen and energy happen in the first stage of photosynthesis?
no
Do plants photosynthesize or cellular respirate?
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
What kind of plant first exhibited photosynthesis?
Impossible to say. However, photosynthetic bacteria were around long before plants.
How did the earth change after some bacteria started using photosynthesis?
Oxygen evolved for first time. Many compounds were oxidised
What is the first thing live in this world?
Probably a form of bacteria. They evolved into multicellular organisms. Some evolved into plants because they could do photosynthesis
What was the major contributor of oxygen to earth?
The major contributor of oxygen to Earth's atmosphere is cyanobacteria, which are photosynthetic bacteria that produce oxygen as a byproduct of photosynthesis. These organisms were among the first to evolve the ability to perform photosynthesis, releasing oxygen into the atmosphere billions of years ago.
What bacterias produces oxygen?
Cyanobacteria or blue-algae are microbes that produce oxygen through the process of photosynthesis. Some scientists believe that these bacteria were the first to produce oxygen on Earth.

How the first plant cell could have evolved?
The first plant cell likely evolved from an ancient photosynthetic bacteria through a process called endosymbiosis, where the bacteria was engulfed by a primitive eukaryotic cell. Over time, the bacteria and host cell developed a mutually beneficial relationship, leading to the evolution of the first plant cell with chloroplasts for photosynthesis. This symbiotic relationship provided an evolutionary advantage, allowing plants to harness sunlight for energy.
The chloroplasts in eukaryotes closely resemble?
The chloroplasts in eukaryotes closely resemble cyanobacteria, as first noted by French scientist Andreas Schimper. Cyanobacteria are bacteria that produce energy for themselves through photosynthesis.
