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
