The Cell
And It’s Organelles
The Cell
 The basic unit of structure and function in
living things
PLANT CELL
ANIMAL CELL
Organelles
 The tiny structures
in the cell that
carry out the
specific functions in
the cell
Entering The Cell


CELL WALL
A stiff wall that
surrounds the cell
membrane, giving the
cell a rigid boxlike
shape
Function: protection &
support
This structure is only
in the plant cell

Structure: Cell Walls
CELL MEMBRANE
 Forms the outside
boundary that
separates the cell
from its
environment
 Function: controls
what comes in and
out of the cell

NUCLEUS
 Acts as the “brain”
of the cell or the
control center
 Where DNA is
found

Nucleus
Nucleus
CYTOPLASM
 A gel-like fluid found throughout the
entire cell where the organelles are
found.
 It is constantly moving so the cell
does not need to propel itself.

MITOCHONDRIA
 The “powerhouses”
of the cell
 Produces energy
for the cell by
respiration

Mitochondria
ENDOPLASMIC RETICULUM
 Carry proteins and other materials from
one part of the cell to another
 Biology4Kids.com: Cell Structure:
Endoplasmic Reticulum
RIBOSOMES
 Factories that produce proteins

Ribosomes
ER
Ribosomes
GOLGI BODIES
 The cell’s mailroom
 Receives proteins and other materials from the
ER, packages them and distributes them to other
parts of the cell.

VACUOLES
 Storage area of the cell
 Stores food and water
 Plants have one large vacuole for
water
 Some animal cells have them &
others do not

LYSOSOMES
 Cell’s cleanup crew
 Breaks down old cell parts and releases the
substances so they can be used again.

CHOLORPLASTS
 Capture energy
from the sunlight
and use it to
produce food for
the cell
 Found only in the
plant cell
