Bacterial StructureĬlick on the numbers to learn more about the parts of a bacterial cell The lower stripe is blue and labelled "Light Microscope." This runs from halfway between the 100 nanometre and one micrometre marks to halfway between the one millimetre and one centimetre marks.Įven though they are small, bacterial cells have many different parts. The top one is yellow and labelled "Electron Microscope." This goes from smaller than one nanometer to the 100 micrometres mark. Below the scale are two thick, coloured stripes. Over the 100 micrometres mark is an illustration labelled "Plant Cell." This is a soft, rounded green rectangle with pointed corners and yellow and dark green shapes inside. Over the ten micrometres mark is an illustration labelled "Animal Cell." The is flat, round, and blue with purple shapes inside. Over the one micrometre mark is an illustration labelled "Bacterium." This is a green capsule shape that looks a bit like a pickle. Between ten and 100 nanometres is an illustration labelled "Virus." This looks like a clear teal gem sitting on a purple pole with thin spider legs around the base. This consists of multicoloured spheres connected by white sticks. Above this marking is an illustration labelled "Small Molecule". The scale starts on the left at one nanometre. Shown is a colour illustration of cell and cell parts along a scale from one nanometre to one centimetre, labelled with the equipment needed to view them. That is much smaller than the human red blood cell, which is about 7 μm in diameter. 1 μm, or micrometre, is 1 000 times smaller than a millimetre. And most of them are only 1 to 2 μm in diameter. Bacterial cells are between about 1 and 10 μm long. Our bodies are made up of trillions of cells.īacteria are much smaller than human cells. This means that each bacterium is made up of only one cell. There are more bacteria living in your mouth than there are people who have ever lived on Earth! Size of Bacteriaīacteria are single-celled organisms. They can live inside the human body, at the North Pole, and even at the bottom of the ocean! They have also adapted to many different environments. Since then, bacteria have evolved into a wide variety of types. These fossils are about 3.5 billion years old! That’s a group of organisms that includes bacteria. In fact, they are the oldest known forms of life on Earth! The earliest fossils we know are of prokaryotes. Bacteria have been around for a very long time.
