Bacteria are simple organisms that are found in every type of environment, including on land, in the air, in water and on and inside plants and animals. A bacterium (or single bacteria) is a single-celled creature that can take many shapes and forms.


Bacteria are living one-celled creatures that most often reproduce by an original cell splitting in half, a process known as binary fission. This process begins once a cell has grown to be big enough — about twice its original size.


Bacteria that make their own food are known as autotrophs or producers, and they do this through the process of photosynthesis or chemosynthesis. Most autotrophs use the process of photosynthesis, which usually involves converting carbon dioxide and water into glucose using the sun?s energy.


The naming of bacteria is done according to the binomial system introduced by Carl Linnaeus. A bacterium has a genus name, which indicates the genus to which it belongs, and a species epithet. Epithets identify subordinate units within a genus. The genus name and the species epithet together form th


Heterotrophic bacteria eat other organisms and absorb dead organic material, while autotrophic bacteria create their own food, according to Medical News Today. Some autotrophs feed themselves through photosynthesis, while others perform chemosynthesis.


Different types of bacteria use various mechanisms to navigate their environments. These methods of movement include using appendages, such as flagella and pilli, using chemical propulsion and joining other bacteria as part of a biofilm.


Bacteria needs water, nutrients, the right temperature range and a certain level of acidity in order to grow. Some bacteria require oxygen to grow, while for others, oxygen prevents growth.


Some bacteria breathe oxygen, but many use other forms of respiration. Strictly speaking, bacteria do not “breathe” as humans and other animals do, but they must still engage in the act of cellular respiration. Cellular respiration is the method by which cells convert chemicals into energy that the


Bacteria multiply through binary fission. This process involves the division of a single cell into two identical daughter cells, and it starts when the DNA of a bacterium divides into two replicates. The bacterial cell splits into two daughter cells that have identical DNA to the parent cell.


Bacteria cells do have organelles, although generally these are fewer in number and less complicated than those found in plants and animals. Most commonly, bacteria contain ribosomes. These organelles are composed of RNA-rich granules located within the cytoplasm and are the site for protein synthes
