Short Answer:
Like instruments in an orchestra, different cells have different appearances and perform different jobs. They
are said to be “specialized” – for particular tasks. Your muscle cells are shaped to move parts of your body
and skin cells are built to protect your body from the sun and other things.
1. Fill out the chart below with the description of each specialized cells job and draw an approximate picture
of what the cell looks like. Use pg. 139 to help you. The first function is done for you.
Cell
Nerve
Blood
Bone
Skin
Muscle
Function
These cells send electrical signals
between the brain and other body parts
through long, finger like fibers (strings)
that reach from one cell to the next.
