Scientists discovered DNA<\/a> of bacteria that\u2019s over half a million years old!<\/p>\n These tiny microorganisms live in a variety of different environments \u2014 in oceans, on rocks, your skin, in your nose, and mouth \u2014 you get it, they\u2019re everywhere!<\/p>\n Let\u2019s dive into the exciting world of a bacterial cell and explore its structure, types of bacteria and all the ways these tiny organisms impact our lives!<\/p>\n Uncover the battle raging within. Read the BIOWARS comic book!<\/a><\/p>\n Bacteria are single-celled organisms that can\u2019t be seen with the naked eye.<\/strong><\/p>\n They are considered living organisms because, unlike viruses<\/a>, bacteria can survive on their own.<\/p>\n Dr. Alex Polyakov<\/strong><\/a>, Associate Professor and researcher at the University of Melbourne, describes bacteria like this:<\/p>\n \u201cBacteria are tiny creatures that are too small to see with the naked eye. They can be found everywhere around us, on our skin, in the soil, and even in the air we breathe.\u201d<\/em><\/p>\n Dr. Polyakov further explains:<\/p>\n \u201cJust like people, not all bacteria are the same, and some are more helpful than others. Some bacteria are good for us, like those that help us digest our food. But others can make us sick.\u201d<\/em><\/p>\n We\u2019ll breakdown the difference between good and bad bacteria soon!<\/p>\n For now, it\u2019s important to understand that bacteria live in a variety of environments<\/strong> and that, no matter how big their impact on us and\/or the environment may be (both good and bad), we can\u2019t spot them without a microscope.<\/p>\n In the BIOWARS comic book, bacteria are personified as Raze<\/a> and Tenzor<\/a>. The two pose a big threat to the well-being of the BICOSMOS and are in constant war against the brave BIOWARRIORS!<\/p>\n Meet the characters of the BIOWARS universe!<\/a><\/p>\n Bacteria have a simple structure<\/strong>.<\/p>\n They are what we call prokaryotic organisms<\/strong>.<\/p>\n This means that bacterial cells don\u2019t have a nucleus<\/a> or organelles<\/strong>. Organelles are tiny structures within the cell membrane that perform many important tasks, such as helping to make proteins, as ribosomes do!<\/p>\n All bacteria contain just one bacterial cell!\u200b<\/p><\/div>\n The main components of a bacterial cell are:<\/p>\n Depending on the presence or absence of oxygen and other environmental factors, bacteria can perform several types of metabolic processes<\/strong>, including:<\/p>\n Aerobic respiration<\/strong> is a process during which bacteria use oxygen to produce energy<\/strong>. Bacteria that can perform aerobic respiration are called aerobes<\/strong>.<\/p>\n Anaerobic respiration<\/strong> is a process that doesn\u2019t require oxygen<\/strong>, so bacteria can perform it in environments without oxygen. Bacteria that can perform anaerobic respiration are called anaerobes<\/strong> and they use nitrate, sulfur, or iron instead of oxygen in their metabolic pathways.<\/p>\n Fermentation<\/strong> is another metabolic process that allows bacteria to generate energy in the absence of oxygen<\/strong>. In fermentation, bacteria break down organic compounds, such as sugars, to produce energy.<\/p>\n Photosynthesis<\/strong> is the process by which bacteria use light energy<\/strong> to produce organic compounds from carbon dioxide and water<\/strong>. Bacteria that are capable of photosynthesis are called phototrophs<\/strong>.<\/p>\n All of these metabolic processes play a crucial role in the survival and replication of bacterial cells.<\/p>\n Cyanobacteria get their energy through photosynthesis.\u200b<\/p><\/div>\n The kingdom of bacteria is diverse and these microorganisms can be classified into several different types based on various characteristics, such as:<\/p>\n Bacterial cells perform many functions that are important to the survival and success of these tiny microorganisms but that also affect us and the world as a whole.<\/p>\n As Jennifer England<\/strong>, a Medical Laboratory Scientist from Orbis Education<\/a> explains:<\/p>\n \u201cWhen we think of bacteria, we think of infections that make us sick, but not all bacteria are bad. Bacteria in our stomach helps us digest food. Bacteria that live on our skin fight bad bacteria when they try to get on us and make us sick. There are also bacteria that live outside that help keep water clean for the fish and the dirt healthy so plants can grow. Some bacteria help breakdown leaves, grass, and sticks so that they can be made into dirt\u201d.<\/em><\/p>\n Some of the key functions of bacteria include:<\/p>\n Explore the difference between good and bad bacteria!<\/a><\/p>\n In the kingdom of bacteria, there are a lot of good guys, but also many troublemakers that can hurt you.<\/p>\n Bacteria can cause diseases in humans though:<\/p>\n To minimize the risk of getting sick from bacteria, it’s important to practice good hygiene and follow food safety guidelines!<\/p>\nWhat Are Bacteria?<\/h2>\n
