![]() ![]() Occasionally they are slightly flat due to their proximity to other cells.īacilli is another of the three basic shapes. One of the three basic shapes, coccus are round cells. ![]() So let’s take a look at some of the strange shapes of bacteria… They vary greatly and are an ongoing area of scientific study and discovery. These shapes can exist as single cells, pairs, clusters, and chains. bacteria, singular bacterium, any of a group of microscopic single-celled organisms that live in enormous numbers in almost every environment on Earth, from deep-sea vents to deep below Earth’s surface to the digestive tracts of humans. This plasmid gives certain bacterium an advantage over other bacteria and can make them resistant to certain antibiotics, for example.īecause they have a rigid cell wall, they maintain distinct and definite shapes – some stranger than others. Sometimes a bacterium also includes an extra circle of genetic material called a plasmid. By contrast, humans have about 10,000 loops of DNA. Their cell structure is less complicated than multicellular organisms, and t heir genetic information is contained in a single loop of DNA. The three basic shapes of bacteria are bacillus (rod-shaped), coccus (spherical-shaped), and spirillum (spiral-shaped). Here are a few more details for those of us that haven’t sat in a science classroom for a while: bacteria are single-celled microbes. These include Cocci (spherical-shaped), Bacilli (rod-shaped), Spirilla (spiral-shaped), Vibrio (comma-shaped), and similar others. ![]()
