The Function of Organelles
Occupations of Organized Organelles
Cell Wall

Found only in plant
cells

Gives support to the
cell

Made of cellulose
fibers
Cell Membrane

ALL cells have one

Separates what’s
inside from
environment

Made of phospholipids
Nucleus




Found only in
eukaryotes
Contains DNA
 The info needed to
make a cell
Is covered by 2
membranes
Nucleolus in middle
 Makes ribosomes
Ribosomes

Found in ALL cells

Make proteins

More ribosomes in a
cell than any other
organelle
Endoplasmic Reticulum


Delivery system
 Delivers proteins
made by ribosomes
throughout cell
Two Parts
 Rough
 Has ribosomes
 Smooth
 No ribosomes
Mitochondria



Powerhouse of the cell
 Sugar is broken down
for energy
Energy released by
mitochondria is stored in
ATP
 Most of cell’s ATP
made here
Animal cells can’t make
own food so we need
these to break down sugar
for energy
Chloroplasts




Found only in plant cells
Contain chlorophyll
Photosynthesis happens in
these
Traps sunlight and
sugar
 The sugar is then
broken down by
mitochondria
Golgi Complex


Packages and distributes
proteins
Proteins are sent here from
the ER
 Then a piece of Golgi
membrane encloses the
protein, pinches off,
and is sent to another
part of the cell or out
of it
Vesicles



A bubble that surrounds
some material in the cell
in order to move it
Lysosomes
 Destroy, get rid of
waste, or protect
Vacuole
 Digests
 Stores water
 Plants have a large
central vacuole
