All living organisms on Earth share the
basic characteristics of life.
http://morguefile.com/archive/#/?q=earth
<image>
Those characteristics include growing and
developing, reproducing, using energy,
and responding to their surroundings.

But, what else do living organisms have in
common?
http://pixabay.com/en/couple-holdinghands-love-together-437987/
<image>
They are all made of cells!

Cells are the building blocks of living
organisms.

The organization of cells is responsible for
the structure and function of living
organisms.
<image>
Living organisms can be categorized as
unicellular or multicellular.

The prefix uni means one, so unicellular
organisms are only made of one cell. The
prefix multi means many, so multicellular
organisms are made of many cells.

The cells within living organisms are
responsible for the structure and function
of the organism.

This characteristic is shared by both
unicellular and multicellular organisms.

Most bacteria on the Earth are
considered unicellular. This means that
one cell is responsible for all the functions
necessary for that cell to stay alive.

http://pixabay.com/en/horse-arabs-stallionride-419235/
Multicellular organisms, like this horse,
are composed of many cells. These cells
are specialized to carry out various tasks.

It is obvious that unicellular and
multicellular organisms are different when
you compare the number of cells they are
composed of.

However, all cells have the same organic
chemistry.
<image>
All cells are made of the elements carbon,
hydrogen, oxygen, and nitrogen
http://pixabay.com/en/lab-researchchemistry-test-217043/
<image>
The arrangement of these chemicals
determines what function the cell will carry
out.

Multicellular organisms have specialized
cells that perform specific tasks.
http://pixabay.com/en/animal-cat-kittenfunny-yawning-339400/
<image>
Muscle cells, brain cells, and nerve cells
are all good examples of specialized cells.
http://pixabay.com/en/man-male-boy-aperson-young-461195/
<image>
Specialized cells work together to keep
the organism alive.
http://pixabay.com/en/nerves-cellsdendrites-sepia-346928/
<image>
For example, your brain cells receive a
signal. That signal then passes through
your nerves to your muscles in order to
respond to your surroundings.

It is important to remember that cells are
the building blocks of organisms, and the
arrangement of cells determines an
organism’s structure and function.

Living organisms can be divided into to
two groups when comparing cells. There
are unicellular organisms and
multicellular organisms.

It is important to remember that the
structure and function of an organism is
determined by the cells within the
organism.

In unicellular organisms, such as bacteria,
one cell is responsible for all the functions
that are essential to the organism
surviving.
http://pixabay.com/en/bacteria-bacterialspecies-imitation-108897/
<image>
Multicellular organisms, on the other
hand, have specialized cells.

Specialized cells are cells that carry out
specific tasks. Blood cells are good
examples of this characteristic of
multicellular organisms.

These elements are used to create the
structure of the cell.

Regardless of the number of cells the
organism is composed of, organisms will
always have the same organic chemistry.

Multicellular organisms often have trillions
of cells.
http://pixabay.com/en/monks-thailandpriesthood-buddhism-472448/

These cells are arranged in a way that
allows them to carry out very specific
functions.
http://pixabay.com/en/buddhism-orangemonks-buddhists-452011/

We call these cells specialized cells.

White blood cells are an example of
specialized cells. Their function is to look
for foreign invaders within your blood
stream as part of your immune system.
