ORGANELLE
LOCATION
DESCRIPTION FUNCTION
cell wall
plant, not animal
*outer layer
*rigid, strong, stiff
*made of cellulose
*support (grow tall)
*protection
*allows H2O, O2, CO2 to pass into
and out of cell
cell membrane
“doorway to the cell”
both
plant/animal
*plant – inside cell
wall
*animal – outer
layer; cholesterol
*selectively
permeable
nucleus
“brain” or “library” of the
cell
both
plant/animal
*large, oval
*support
*protection
*controls movement of materials
in/out of cell
*barrier between cell and its
environment
*maintains homeostasis
*directs cell activities, control
center
nuclear membrane
both
plant/animal
*surrounds nucleus
*selectively
permeable
*controls movement of materials
in/out of nucleus
cytoplasm
both
plant/animal

plant/animal
both
plant/animal
both
plant/animal
*clear, thick, jellylike
material inside cell
*network of tubes or
membranes
*small bodies free or
attached to E.R.
*bean-shaped with
inner membranes
*supports/protects cell organelles
plant – few/large
animal – small
plant –
uncommon
animal – common
plant, not animal
*fluid-filled sacs
endoplasmic reticulum
(E.R.) “passage way”
ribosome
“protein factory”
mitochondrion
“power plant”
vacuole
“storage tank”
lysosome
“digestion/destruction”
chloroplast
“green”
“power plant for the cell”
golgi apparatus
“packaging center”
both
plant/animal
nucleolus
both
plant/animal
Chromatin/chromosomes both
(made of DNA)
plant/animal
*small, round, with
a membrane
*green, oval usually
containing
chlorophyll (green
pigment)
*looks like the E.R.,
but is located closer
to the cell
membrane
*looks like a “small
nucleus” inside the
big nucleus
*thin strands of
material in the
nucleus
*carries materials through cell
*produces proteins
*converts food energy (sugar)
into cellular energy (ATP) =
cellular respiration
*store food, water, waste
*breaks down larger food
molecules into smaller molecules
*digests old cell parts
*converts light energy (sun) into
food energy (sugar) =
photosynthesis
*processes, packages & transports
materials sent from the E.R.
*stores materials to make
ribosomes in the cytoplasm
*directs the activities of the cell
*passes on traits of the cell to new
cells
