Stages of the Biological Organization
Biological organization Stages of the Biological Organization Molecular Assemblies These assemblies are organized sets which comprise one or more molecular entity. The microtubule (conveyor belts inside the cells) and the cell membrane (plasma membrane) are a typical example of organized molecular assemblies. Cell All living organisms in the biological organization consist of structural and functional units called cells. For example, bacteria, amoeba, archaebacteria, etc, are all single-celled organisms. Humans and many other organisms are multicellular, which may have around 100,000,000,000,000 cells! Tissue A group of cells which may or may not have similar characteristics is termed as a tissue. Each tissue is attributed with a particular set of functions in the body of the living organism. Connective tissue, muscle tissue, nervous tissue and epithelial tissue are the tissues in animals, while meristematic tissues and permanent tissues are those of the plants. Organ Now when the different types of tissues are organized or grouped together, they form what is known as an organ. These tissues enable a particular organ to carry out its own specific task. Examples are heart, lungs, kidneys, stomach, etc. Organism Plants, animals, humans, bacterium, etc., and any form of life is known as an organism. It can be regarded as the complete framework of organ systems, organs, organelle and all other components which work in their own specific way in order to carry out the various processes of life. Population Now we come to a broader part in the levels of a biological organization. A group of inter-breeding organisms of the same species inhabiting a defined area is termed as a population. For example, the population of mice in a barn. Biosphere Biosphere is simply defined as the regions on, below, and above the surface, and atmosphere of the Earth where living organisms exist. The biosphere can range from the atmosphere to a very cold environment and from the deep-sea vents of the ocean depths to a very hot environment.Stages of the Biological Organization

Biological organization Stages of the Biological Organization Molecular Assemblies These assemblies are organized sets which comprise one or more molecular entity. The microtubule (conveyor belts inside the cells) and the cell membrane (plasma membrane) are a typical example of organized molecular assemblies. Cell All living organisms in the biological organization consist of structural and functional units called cells. For example, bacteria, amoeba, archaebacteria, etc, are all single­celled organisms. Humans and many other organisms are multicellular, which may have around 100,000,000,000,000 cells! A group of cells which may or may not have similar characteristics is termed as a tissue. Each tissue is attributed with a particular set of functions in the body of the living organism. Connective tissue, muscle tissue, nervous tissue and epithelial tissue are the tissues in animals, while meristematic tissues and permanent tissues are those of the plants. Tissue Now when the different types of tissues are organized or grouped together, they form what is known as an organ. These tissues enable a particular organ to carry out its own specific task. Examples are heart, lungs, kidneys, stomach, etc. Organ Plants, animals, humans, bacterium, etc., and any form of life is known as an organism. It can be regarded as the complete framework of organ systems, organs, organelle and all other components which work in their own specific way in order to carry out the various processes of life. Organism Now we come to a broader part in the levels of a biological organization. A group of inter­breeding organisms of the same species inhabiting a defined area is termed as a population. For example, the population of mice in a barn. Population Biosphere is simply defined as the regions on, below, and above the surface, and atmosphere of the Earth where living organisms exist. The biosphere can range from the atmosphere to a very cold environment and from the deep­ sea vents of the ocean depths to a very hot environment. Biosphere Particles starting right from the subatomic state to the organism state, are included in the levels of biological organization. As you can infer, every component in one level is linked with the other in the next level and so on. It can be referred to as a biological chain wherein, all the factors are       interdependent on each other.
