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.Learn More
The five kingdoms of living things are Monera, Protista, Fungi (or Mycota), Plantae (or Metaphyta) and Animalia (or Metazoa). The kingdom is the third taxonomic rank in the biological classification system.Full Answer >
The phospholipid bilayer's function is to maintain a barrier between the cell and its external environment and to store and transport a variety of proteins that are essential to the cell's function. It controls what enters and exits the cell.Full Answer >
Fungi are structured in filaments called hyphae, which are made up strings of cells and separated from one another by septa or crosswalls. Many of these hyphae grouped together make up mycelium.Full Answer >
The process of breathing performs a number of important gas exchanges through inhalation and exhalation. When someone inhales, they contract and move their diaphragm, which allows the lungs to expand. This is a part of the process needed to psychically suck in the air. When a person exhales, the diaphragm relaxes and the movement is undone. This allows air to be gradually pushed out of the lungs.Full Answer >
