Study Pack #7
Today’s Goal…

I can describe the levels of organization
within an organism.
Before we begin…

Card Sort


Work with your partner to put the cards in
order from simplest (or smallest) to most
complex (or largest)
Discuss why you have chosen this order
Cell Teamwork

For unicellular organisms the single cell
performs all life functions

Bacteria
Cell Teamwork

In multicellular organisms cells have
special functions and work together for the
good of the organism


Plants
Animals
Levels of Organization





Cells
Tissues
Organs
Organ Systems
Organisms
Cells



Basic unit of structure and function in
living things
Serve a specific function
Examples




Blood cells
Muscle cells
Bone cells
Brain cells
How do you think these cells
are different in structure and
function?
Tissues


Made up of similar cells that work together
Examples




Epithelial (skin) tissue
Connective (tendons, ligaments) tissue
Muscle tissue
Nerve tissue
Organs


Made up of tissues that work together
Examples



Heart
Brain
Skin
Organ Systems


Two or more organs that work together
Examples



Skeletal System
Muscular System
Nervous System
Organisms


Living things
However, living things may also just be
made up of one cell (bacteria)

One More Step!

What makes up cells?


What makes up organelles?


Organelles
Molecules - atoms bonded together
What makes up molecules?

Atoms (elements from the periodic table)
Put these in order…

From simplest to most complex
