1.3 Cell Differences
(p40-43)
Cell Development
All cells start their lives as
________________________cells called
___________________________.
Stem Cells
Each stem cell has the potential to become
a _____________________________________ as it
matures.
Some will become _________________ cells,
some ____________________ cells, and some
______________________ cells.
Cell Specialization
Different types of cells have
___________________________________________ and
_________________________ that enable them to
perform their functions efficiently.
Cell Differentiation
___________________________________________: This
is the series of events through which
_________________________________ develop into
________________________________
Scientists are very interested in studying
how stem cells differentiate.
They might be used to _____________________
or _____________________damaged tissues in
humans.
Specialized Cells
Each different kind of cell has different
structures that allow them to perform a
__________________________________________.
There are ___________ different types of cells
in the human body.
We will be looking at only _________________
of these in more detail.
Specialized Cells Structure and
Function
Muscle Cells
Nerve Cells (Neurons)
Red Blood Cells
Bone Cells
Skin Cells
