In biology, an organism (from Greek: οργανισμός, organismos) is any individual entity that exhibits the properties of life. It is a synonym for "life form". Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi; or unicellular microorganisms such as a protists, bacteria, and archaea.[
Defining Life
Five characteristics are used to define life. All living things share these characteristics. All living things:
are made of one or more cells.
need energy to stay alive.
respond to stimuli in their environment.
grow and reproduce.
maintain a stable internal environment.
Humans are multicellular animals composed of many trillions of cells which differentiate during development into specialized tissues and organs. An organism may be either a prokaryote or a eukaryote. Prokaryotes are represented by two separate domains—bacteria and archaea. Eukaryotic organisms are characterized by the presence of a membrane-bound cell nucleus and contain additional membrane-bound compartments called organelles (such as mitochondria in animals and plants and plastids in plants and algae, all generally considered to be derived from endosymbiotic bacteria). Fungi, animals and plants are examples of kingdoms of organisms within the eukaryotes.
Living Things Are Made of Cells
Cells are the basic building blocks of life. They are like tiny factories where virtually all life processes take place. Some living things, like the bacteria, consist of just one cell. They are called single-celled organisms. Some living things are composed of a few to many trillions of cells. They are called multicellular organisms.
