CELL PARTS
AND FUNCTIONS
PART
Plant
Animal
or
Both?
PICTURE
FUNCTION
 Regulates what enters and leaves
the cell
 Separates inside reactions from
outside reactions
Cell Membrane
BOTH
“gatekeeper”
Nucleus
BOTH
 Controls most of the cell’s
functions
 Houses and protects the cell’s
genetic information (DNA)
“control center”
Nucleolus
BOTH
 Makes ribosomes
Mitochondria
BOTH
Transfers energy from organic
molecules to ATP (which powers all of
the cell’s activities)
“powerhouse”
Ribosomes
BOTH
Builds proteins
BOTH
Provides a pathway for molecules to
move within the cell
Endoplasmic Reticulum
“intracellular highway”


SER: no
ribosomes
Smooth
RER:has
ribosomes
(why rough)
Rough
Lysosome
Animal
SER: builds lipids (cholesterol & sex
hormones), releases calcium
RER: produces phospholipids and
proteins
Contain digestive enzymes that break
down large molecules
“recycling center”
Golgi Apparatus
BOTH
Modification and packaging of
molecules for export from the cell
Plant
Large fluid-filled organelle that stores
H2O, enzymes, and wastes
Cell Wall
Plant
Rigid layer that contains cellulose,
provide structural support to the cell
Chloroplasts
Plant
Use light energy to make
carbohydrates from CO2 and H2O
during photosynthesis
“post-office”
Vacuole
“water tank”
Cytoskeleton
Network of
thin tubes
and filaments
 Hold organelles in place, maintain
cell’s shape, act as tracks for
organelle movement

Microtubules
BOTH

Microfilaments
BOTH
 Contribute to cell movement

Cilia/Flagella
Animal

Centrioles
Animal
 Assist in cell movement (cilia –
short, hair -like; flagella – long,
whip-like)
 Help with cell division
