Eubacteria are prokaryotic, single celled, microscopic organisms. They produce asexually by splitting in half. They can be spirilla, cocci, or bacilli shaped. They have free floating DNA surrounded by cytoplasm. Inside the cytoplasm are ribosomes, and they have a cell wall to hold these together. These are different from archaebacteria because their chemical makeup is different; their cell walls have peptidoglycan. Some have cilia and some have flagella to help them move around. Some are heterotrophic and some are autotrophic. Some make vitamins and foods, but some are bad and can give you strep throat. they live in soil, springs, water, organic matter, and on plants and animals. They are important because they turn dead and unusable material into reusable material. If they did not break waste down, it would keep building up and the earth would have toxins everywhere. They also break down some material in our body so we can use it.
Archaebacteria are single celled, prokaryotic organisms. They live in very extreme conditions such as hot boiling water or thermal vents. They can even live in highly acidic environments, or areas with no oxygen. They can be autotrophic or heterotrophic; they can obtain their food from decaying plants and animals, or they can make their own food from chemicals around their environment. They can help in making antibiotics, sewage treatment, and production of solvents. they also have free floating DNA, and ribosomes held in cytoplasm; they are also surrounded by a cell wall. They come in spirilla, cocci, or bacilli shapes. Archae also use flagella and cilia to move. Archaebacteria are different because their cell wall does not contain peptidoglycan. The lipids inside are also linked differently than eubacteria.
