Prokaryotes

=Basic Information of Prokaryote= Prokaryotes are single celled organisims just like bacteria. There are two main types of prokaryotes there is Bacteria and Archaea. There are many differences between eukaryotes and prokaryotes but the main difference is that prokaryotes do not have a nucleus while eukaryotes do. All of the prokaryotes genetic material is stored inside a DNA molecule. And that DNA molecule is found inside the nucleiod region. The nucleiod region is protected by the cell wall. Prokaryotes are asexual that means that there offspring have the exact same characteristics as the parent cell. Prokaryotes are found all over the world they make up a large part of the biomass of Earth. =Different types of Prokaryotes= There are two different types of prokaryotes. There are photosynthetic and chemosynthetic prokaryotes. Photosynthetic prokaryotes have a extension on the plasma membrane and they are called thylakoids. Many other molecules are found in the thylakoid membrane. Chemosynthetic prokaryotes obtain energy to make organic food. Many Chemosynthetic prokaryotes are anaerobic and they are mostly found in swamps and lakes. The other type of prokaryotes is the heterotrophic prokaryote. They eat digested material and they are also anaerobic. There are three different types of Heterotrophic prokaryotes and they are Saprotrophic, parasites, and mutualistic. You can also classify the different types of prokaryotes by the different stainnig techniques that they have. =Bacteria and Archaea= Bacteria serve many functions to the Earth. Bacteria serves as a decomposer, fermentation, and it has an important role in our digestive system. Bacteria is also involved in the nitrogen cycle it brings nitrogen in the soil for plants. Prokaryote cells have many shapes but there are four main shapes they are cocci, bacilli, vibrio and spirochaete. Archaea which are micobes live under extreme conditions. Archaea is the oldest form of life on Earth. It does not need sunlight or oxygen in order for it to survive. It absorbs CO2, N2, and H2S. And it lets of methane gas as a waste product.
