 Microtubules
 Intermediate
Filaments
 Microfilaments
Date
Functions & Other Info
 Network of proteins that crisscross
entire cell
 Provide internal structure and
tracks for molecular and organelle
movement
 Long hollow tubes
 Give cell shape
 Act as tracks for movement of
organelles
Give cell its strength
Tiny threads that enable cells to move
and divide.
Important in muscle cell contractions

Functions & Other Info
 Location of many chemical
reactions
 Fills space between nucleus and
cell membrane
 Fluid portion = cytosol
 Storehouse for genetic info
(DNA)
 Contains instructions for making
proteins
 Controls all of cell’s activities
 Interconnected network of
folded membranes
 Ribosomes attached
 Helps in making proteins
 Interconnected network of
folded membranes
 Helps in making lipids
 Breaks down drugs & alcohol

Vesicles

Vacuole
Functions & Other Info
 Link amino acids together to
make proteins
 Can be free floating in cytoplasm
or attached to ER
 Process, sort and deliver
proteins
 Layered stacks of membranes
 Isolate and transport specific
molecules
 Short-lived & are formed and
recycled as needed
 Supply energy to the cell
 Bean shaped & contain inner
folded membrane
 Perform cellular respiration –
burning of sugars to make
cellular energy (ATP’s)
 Fluid filled sac used for storage
of materials
 Animals – many small vacuoles
 Plants – one large central
vacuole filled with watery fluid
that strengthens the cell and
helps to support the plant

Functions & Other Info
 Membrane-bound organelles
that contain enzymes
 Defend a cell from invading
bacteria and viruses
 Break down damaged or worn
out cell parts
 Centrosome :produces
microtubules
 Centrioles (animal cells) assist in
cell division
