Organization of Living
Things Vocab
Cells: The smallest unit of life
capable of carrying on life's
functions
Tissues: A group of similar cells
that work together to perform
a specific function
Organs: Consists of different
kinds of tissues that function
together
Organ Systems: A group of
organs that work together to
perform a major function
Organism: A living thing.
This type of cell is found all over the body,
usually under the skin. We were born with
the same number of this kind of cell as we
have now. This cell's function is storage.
When we exercise and eat healthy foods the
storage gets depleted. When we don't
exercise and we eat what we want these cells
get bigger. What type of cells are shown?
1. All living things are composed of cells.
2. Cells are the basic units of structure and
function in living things.
3. All cells are produced from other cells.
CELLS: Plants and animals are
made of cells. Cells form the
basic "building blocks" for living
things. Some cells have
specialized functions.
Let's look at various human
cells.
This type of human cell has long
structures that connect to other's of
it's kind. This cell's function is
communication. What type of cell is
this? What purpose do these long
structures have?

This cell's function is to carry oxygen,
waste and nutrients throughout the body.
It is circular to fit through a circular
tube. What type of cell is it?

This cell's job is to destroy invading
organisms. It also removes dead or
damaged cells.

Why do cells have different
sizes and shapes?

TISSUES: A GROUP OF
SIMILAR CELLS WORKING
TOGETHER TO PERFORM A
SPECIFIC FUNCTION

ORGANS: Consists of
different kinds of tissues
that function together
Brain
The brain
consists of
nervous tissue,
as well as
connective
tissue that
supports and
protects.
ORGANISM: Any living thing
that is made up of cells and
performs the 7 functions
of life.

ORGAN SYSTEMS: A group of
organs that work together
to perform a major
function.
The Nervous System
Consists of the brain,
spinal cord and
nerves throughout
the body. It directs
the body's activities
and processes.
Organization of Living Things
Cells make tissues, tissues make
organs, organs make systems, systems
make the organism.
