Examples of Bacteria
Bacteria are a type of living beings or cells that do not have a cell nucleus. Bacteria are single-celled, as well as more primitive than eukaryotic cells (such as those of animals and plants).
Bacteria are usually between 0.5 and 5 microns in size, but there are rare cases of bacteria visible to the naked eye or with simple optical tools such as magnifying glasses or light microscopes.
Bacteria are the largest kingdom of nature , so much so that it is believed that 90% of existing bacteria have not been discovered or cataloged, this despite the fact that practically all bacteria can be reproduced in the laboratory with relatively simple procedures.
Bacteria are a fundamental part of the ecosystem , natural processes and food chains in nature as well as for humanity, since some cause diseases of different degrees of severity or mortality while others are used to produce food such as yogurt, cheese, ferments. , etc.
Bacteria can have the shapes of spheres, rods, spirals, capsules , as well as have flagella or they can move with the natural currents of air or water.
