Cells
What’s Inside a Cell?
All cells consist of a
___cell membrane that is
filled with organelles.
Inside the cells of most
organisms is a major
structure called the
nucleus. In addition, plant
cells have a cell wall and
chloroplasts.
The Cell Membrane
The cell membrane is a
thin, flexible, outer
________that
controls the
“skin”
movement of materials in
and out of the cell.
It also hold the cell
together and gives the cell
its __________.
shape
The Nucleus
The nucleus is the
COMMAND CENTER or
BRAIN for the cell. It is
usually found near the
center and is the “boss.”
The nucleus controls all of
a cell’s activities.
The Cytoplasm
Cytoplasm is the name for
all of a cell’s living material
except the nucleus. It is 7080% water and somewhat
like ___________.
It is
Jell-O
crowded with different
organelles (a small part
___________
of the cell).
Mitochondria
They are compared to A
POWER HOUSE. They
release energy by using
oxygen to burn the fuel
that comes from food.
Vacuoles
These are the cell’s
____________
storage organelles.
They store water and
nutrients until the cell is
ready to use them. They
also store waste until it is
ready to get rid of it.
Endoplasmic Reticulum
A network of passages that
help make and
transport proteins.
_____________
Proteins are needed for
_________,
growth repair, and
replacement of cells. They also
contain ribosomes which
make proteins.
Surrounds the

highway”
Golgi Bodies
A stack of flat, pancakeshaped discs that modify,
sort, package, and store
carbohydrates and
_______________
proteins until they are
needed. They also make
lysosomes.
Lysosomes
Round organelles that
_____
______ cell
Digest
nutrients. They are the
garbage collectors of
___________
the cell.
