Cyanobacteria, algae and tracheophytes are organisms that perform photosynthesis. These organisms absorb large quantities of sunlight, which is then converted into energy. During the process of photosynthesis, the organisms combine sunlight with water, which produces a sugary substance called glucose.
Many different organisms undertake photosynthesis, including higher plants, (tracheophytes), algae and bacteria. Photosynthesis is performed primarily on land, although some aquatic species photosynthesize as well. Regardless of where they produce photosynthesis, organisms use different methods and techniques for performing the process. Cyanobacteria are the only prokaryotes, according to CS, that perform photosynthesis. Cyanobacteria take in carbon dioxide and nitrogen dioxide to carry out photosynthesis and in turn release nitrogen into the surrounding air. Cyanobacteria live in extreme environments and have the ability to regulate the chemical composition of local atmospheres through the photosynthesis process. Algae, like some varieties of cyanobacteria, perform photosynthesis primarily underwater. All species of algae perform photosynthesis. Algae perform aerobic photosynthesis, which means that they use oxygen in addition to sunlight and water to photosynthesize. Like cyanobacteria, algae can adapt to harsh environments and may reside in hot springs, Arctic ice, and temperate oceans. Lastly, tracheophytes perform photosynthesis and have vascular systems to do so.
