WHAT ARE YOU MADE OF?
Cells
Cells
A typical
animal cell
FIRST STOP
The cell membrane
THE CELL
MEMBRANE
• The CELL MEMBRANE
is the “Gate Keeper”
• It controls what goes in
and out of the cell.
NEXT STOP
Cytoplasm
CYTOPLASM
• CYTOPLASM is the gel-
like material inside of the
cell.
• It provides a moist
medium for materials to
move.
NEXT STOP
The nucleus
NUCLEUS
• The NUCLEUS is
the “brain” of the
cell
• It controls all of the
cells’ activities
• The nucleus
contains the cells’
instructions, or
DNA
NUCLEUS
• Some activities directed by the NUCLEUS
include:
• Making copies of itself
• Making repairs
• Getting rid of waste
NEXT STOP
The Endoplasmic
Reticulum
ENDOPLASMIC RETICULUM
• The ENDOPLASMIC
RETICULUM is the
pathway for moving newly
made proteins through the
cell.
NEXT STOP
Ribosomes
RIBOSOMES
• RIBOSOMES are located both on the
endoplasmic reticulum as well as free
floating within the cell.
• Their job is to make proteins.
NEXT STOP
The mitochondria
MITOCHONDRIA
• The MITOCHONDRIA is often called the
“powerhouse” of the cell.
•
Its job is to release energy.
NEXT STOP
The Golgi Body
GOLGI BODIES
• GOLGI BODIES are nicknamed the “post
office” of the cell.
• They package up and deliver materials to
be used within the cell.
NEXT STOP
The cytoskeleton
CYTOSKELETON
• The CYTOSKELETON gives
the cell a stable structure.
• Other important tasks:
• Act as “highways” to move
materials and organelles.
• Pulls apart chromosomes
(DNA) during cell division
and replication.
LAST STOP
The Lysosome
LYSOSOMES
• LYSOSOMES are the “garbage disposals” of
the cell.
•
They engulf, digest and get rid of cellular
waste.
Plant cells
are a little
different
Plant cells have:
Vacuole
Chloroplast
Cell Wall
VACUOLE
• VACUOLES are used
to store sugar or
water
CHLOROPLAST
• CHLOROPLASTS
contain chlorophyll, it's
what makes plants green
• They turn sunlight into
sugar to be used for
energy through a process
called photosynthesis
CELL WALL
• CELL WALLS provide
additional strength and
structure to the plant
• Without cell walls plants
would fall over.
Bacterial cells have:
In addition, bacteria have
ribosomes and DNA
Cilia
Hair-like structures
that help bacteria
move
Flagela
Whip tail structure
that helps bacteria
move
