Breifly define and give an example of each of the five levels if organization in multicellular organisms

The specific living organism possesses only one cell that performs all functions. Multicellular organisms have many parts that are required for survival. These parts are classified into levels of the organization. Five levels of organizations of multicellular organisms exist they are cells, tissue, organs, organ systems, and organisms.

Explanation:

All living organisms are built up of cells. This cell characteristic distinguishes living things from other objects. Cells are the basic building blocks of all organisms. Though cells are made of smaller parts, none of those parts could survive on their own. Cells are the simplest level of organization.

        example: Blood cells, nerve cells

Cells together form the tissue. The cells involved are specialized to cooperate with one another to accomplish one common goal. There are many different types of tissue in both plants and animals.

        example: connective, epithelial, muscle and nerve.

Layers of tissue work together and form an organ. All animals contain organs.Mammals have five vital organs  without that they cannot live  

        example: kidneys, lungs, liver, heart, and brain

Organs work together and form organ systems. Organ systems keep the body regulated and in a stable state. Organ systems often work together and rarely work in isolation. The human body has 11 organ systems.

        example: circulatory system, nervous system, skeletal system

Organisms are of any form that can carry out its own functions. Some fully functioning organisms are made of just one cell. For the level of organization, organisms are made up of many organ systems working together.

        example: Human, Plants, bacteria, animals
