What are bacteria?
Bacteria are unicellular organisms with simple cells with a very low level of cellular differentiation. Bacteria can grow as single cells or as colonies of cells. They can get food in various ways. They can produce their own food, making them known as producers, or when they depend on other organisms for their food, they are called consumers. Some can move with the help of flagella or fimbriae-like structures, while others are immobile.
What is a supporter?
Protists are the most diverse organisms and they are difficult to classify because some of them have plant-like, animal-like or fungal-like characteristics. They are more evolved than bacteria, so they exhibit a higher degree of cellular structural differentiation. Compared to bacteria, protists are more complex.
Although both organisms evolved from the same ancestor, there are some key differences that separate them.
Bacteria are the oldest living organisms known to exist on Earth. They belong to the oldest kingdom, Monera, while the Protists are classified as Kingdom Protista. They are organisms that display characteristics similar to those of animals, plants or fungi. Therefore, they are further classified into 3 categories, namely plant-like protozoa, animal-like protists or fungus-like protists.
Differences in Cell Structure
Bacteria are single-celled organisms, and their cell structure is very simple. The absence of a nucleus is the primary controller of the cell. DNA, the genetic material, is scattered throughout cells. Since they do not contain a nucleus, they are called prokaryotes. They do not contain any small specialized small organs called organelles. They can be rods, spirals, spheres, chains, etc.
Protists can be unicellular or multicellular. They contain a nucleus as well as specialized small organelles. Furthermore, their genetic material is compact within the envelope.
Differences in Habitat
Bacteria can be found almost everywhere. They are a major part of the population in the environment. Protists are only found in moist environments.
The Importance of Bacteria and Drugs
Although bacteria are known to cause disease in humans, they are also beneficial in many ways. They maintain a healthy balance in the environment. They maintain the food chain in the environment through the process of recycling nutrients. They are also present in the human gut and support health by producing vitamin K and vitamin B12. They are used in industries that make bread, alcohol, yogurt and cheese.
Primitive organisms are equally important for maintaining the balance of the ecosystem. They are responsible for providing the oxygen needed for breathing.
Bacteria and protists are important organisms that destroy the primary environment around us. Although they evolved from a common ancestor, there are certain important differences that suggest the evolutionary process between these two organisms. In contrast to bacteria, protists have a highly evolved and well-defined cellular structure. Protists can only be found in moist environments, while bacteria are found everywhere. Bacteria are unicellular whereas protists can be unicellular or multicellular.
