The 5 Kingdoms of Living Beings
All living organisms are classified into five realms, from small bacteria to humans, this classification has a fundamental foundation that was established by scientist Robert Whittaker, who contributed greatly to the study of beings living on Earth.
- Want to know more about them? In this article by Animal Expert we will talk about the classification of living beings into five realms and their main characteristics.
Robert Whittaker, a major plant environmentalist in the United States who focused on the analysis of plant communities, was the first person to propose that all living beings be classified into five kingdoms.Whittaker relied on two key characteristics for its classification:
Combining the characteristics that make up the previous two classifications, Whittaker ranked all living beings into five realms: Monera, Protista, Fungi, Plantae, and Animalia.
The kingdom of Monera includes single-celled prokaryotic organisms. Most of them are fed by absorption, but some are able to perform photosynthesis, as is the case with cyanobacteria.
Within the kingdom of Monera, we find two subbreines, the archobacteria, which are microorganisms that live in extreme environments, such as places at very high temperatures, such as thermal trenches at the bottom of the ocean, and also the subbreine of eubacteria.We can find eubacteria in almost every environment on the planet, they play an important role in life on Earth and some cause disease.
This area includes single-celled eukaryotic organisms and some simple multicellular organisms.There are three main sub-royalties in the protist kingdom:
The fungal kingdom is made up of multicellular eukaryotic organisms that are fed by absorption.Most of them are decomposing organisms that secrete digestive enzymes and absorb small organic molecules released by the activity of these enzymes.In this kingdom there are all kinds of mushrooms and mushrooms.
This area includes multicellular eukaryotic organisms that perform photosynthesis, through this process plants produce their own food from the carbon dioxide and water they capture, the plants do not have a solid skeleton, so all their cells have a wall that keeps them firm.
They also have multicellular sex organs and form embryos during their life cycle.The organisms we can find in this kingdom are, for example, mosses, ferns and flowering plants.
This kingdom is composed of multicellular eukaryotic organisms. They feed by ingesting, ingesting food and digesting it in specialized cavities of your body, such as the digestive system of vertebrates.None of the organisms in this kingdom have a cell wall, which occurs in plants.
The main characteristics of animals is that they have the ability to move from one place to another, more or less voluntarily, all animals on the planet belong to this group, from sea sponges to dogs and humans.
