7.12D Cell Organelle Structure vs Function
Organelle
Structure – physical properties,
like shape, color, and location
Cell Membrane Surrounds the cytoplasm and
(Plasma
other organelles
Membrane)
Cell Wall
Rigid; surrounds plant cells
Nucleus
Function – job or role an
Kind of cell
organelle does for the cell
found in?
Allows things to enter and exit Both plant and
the cell; gets rid of waste
animal cells
provides support, protection
Houses chromosomes / DNA – Control center, tells other
the genetic code (heredity
organelles what to do
material)
Cytoplasm Gel-like liquid that fills the cell Provides suspension to
organelles so they move
around easier
Mitochondrion Double membrane organelle
Converts glucose molecules
(Mitochondria) with inner folds
into energy
Chloroplast
Vacuole
Lysosome
Filled with chlorophyll;
Contains stacks of discs
Much larger in plant cells than
animal cells
Small, circular organelle that
contains enzymes
Plant cells only
Both plant and
animal cells
Both plant and
animal cells
Both plant and
animal cells
Site of photosynthesis – which Plant cells only
makes food for plant cells
Storage site of water,
Plant - large,
nutrients, and waste
central
animal -small
Digest old cells parts; Aids
Animal cells
with removal of waste

Organelle
Cilia
Structure
Hair-like projections
Function
Aids in movement
Flagellum
Tail-like projections
Aids in movement
Centriole
Found in pairs; tube-like
structures in a cylinder pattern
Ribosomes
Small dots; attached to ER or
float freely in cytoplasm
Endoplasmic Flattened sacs/tubes;
Reticulum
connected to nucleus; smooth
or rough (ribosomes attached)
Golgi Bodies Curved shaped sacs; Contain
(Golgi Apparatus enzymes; found between the
/Complex)
ER and cell membrane
Nucleolus
Found inside nucleus; no
membrane; contains proteins
and nucleic acids
Cytoskeleton Fibers found in the cytoplasm
Aids in cell division
(mitosis)
Synthesizes protein
(production)
Transports proteins and
other molecules around
the eukaryotic cell
Packages proteins
Found in?
Some animal cells;
unicellular
organisms

Aids in production of

All cells
Acts like a skeleton and
muscles; Aids in shape,
support, and movement
