What is the Meaning & Definition of Kingdom Animalia

The name of Kingdom Animalia is the one that is used to refer to the Kingdom composed of animals and that is without a doubt, the best known by humans (who are also part of it). The Kingdom animalia is characterized by having members who manage to develop mobility own unlike what happens with the members of the Kingdom of plants or fungi. Animals occur on planet Earth as diverse as very important, having thousands of species but also a differentiation based on the type of cells that compose them, the type of power that develop, etc. Unlike what happens for example in the Kingdom monera, composed mainly of single-celled organisms (i.e., from a single cell), the Kingdom animalia is composed of multicellular organisms, which means that its organizational structure is much more complex and, depending on the type of animal and their species, physical appearance will also be much more complex. At the same time, this variety of cells that are found in the formation of the animals is what allows the existence of so many variants in regards to size, color, type of hair or skin, form of power, etc. Animals, unlike bacteria, are eukaryotic organisms, which means that in all of its cells there is a well defined, container core of genetic material specific to each specimen.
Another feature of great importance in the Kingdom animalia, that distinguishes these beings of fungi and plants, is that all its members are heterotrophic. In other words, be heterotroph means that food should be looked for on the outside of your body since they cannot produce it for themselves (like plants do). In addition, all of them also consume oxygen, in greater or lesser extent.
Finally, all animals have a process of existence which is characterized by the reproduction and development, time in which the body will slowly acquiring those typical features of its kind and that will give you the final aspect.
