explain in detail living organism
Answers
Answer:
An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on earth. These organisms may be classified in various ways. One of the ways is by basing upon the number of cells that make it up. The two major groups are the single-celled (e.g. bacteria, archaea, and protists) and the multicellular (animals and plants). Organisms can also be classified according to their subcellular structures. Those with a well-defined nucleus are referred to as eukaryotes whereas those without are called prokaryotes. Both of them possess a genetic material but the location differs. In eukaryotes, the genetic material is found inside the nucleus whereas, in prokaryotes, it is located in a special region called a nucleoid. A modern system of classification groups living things into three distinct domains: (1) Archaea (archaebacteria), (2) bacteria (eubacteria), and (3) Eucarya (eukaryotes). Both archaea and bacteria are prokaryotic organisms while Eucarya, as the name suggests, it includes all the eukaryotes. The scientific study of all organisms is called biology. Biology is a field in science that aims to study the structure, function, distribution, and evolution of living things.
Living Organisms
An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of cells in which organelles or organs work together to carry out the various processes of life.
