LEVELS OF ORGANIZATION IN LIVING THINGS
All living things are organized into several basic levels of organization.
Starting with the smallest and going to the largest it goes… Cell -> Tissue ->Organ ->Organ system ->
Organism
Cell
The basic level of Organization for all living things is the cell.
Complex organisms are composed of many cells
Examples:Heart CellBrain CellMuscle Cell
Tissue Within an organism groups of cells with
similar functions combine to make up tissues.
A tissue is a collection of cells working together to perform a specific job
FOUR BASIC TISSUESConnective TissueNervous TissueMuscle TissueEpithelial Tissue
Organ Two or more types of tissues that
work together to complete a specific task
Examples:HeartBrainMuscleSkin
Organ Systems Group of organs working together for a
common goal combine to make up organ systems
Example:Cardiovascular / Circulatory SystemNervous SystemMuscular System
Organism Several organ systems working together
combine to make up an organism. An organism is an entire living thing that
can carry out all basic life processes. Examples:HumanDogTurtleTree

several organ systems. We will be discussing 7 in this class.
