Concept Map of Cellular Structures
- Microtubules
- Structure
- Long and hollow
cylinders that
consist of subunits
of the protein
tubulin.
- Function
- They form a dynamic
scaffolding for cellular
processes. They assemble
when needed and
disassemble when not
needed.
- Plasma Membrane
- Structure
- Membrane that
encloses the cell which
is composed of a bilayer
of proteins.
- Function
- Selectively controls the kinds and
amounts of substances moving in
and out of the cell. (selectively
permeable)
- Extracellular Matrix (ECM)
- Structure
- Structure differs among
groups but it is in most
cases a wall.
- Function
- Protects, supports, and
imparts shapes of the
cell.
- Intermediate Filaments
- Structure
- Fibrous proteins
(lamina) coiled
together.
- Function
- Stable cytoskeletal
element that supports
cells and tissues.
- Microfilaments
- Structure
- Fibers that
consist of
subunits of
actin.
- Function
- Strengthen or change
the shape of eukaryotic
cells.
- Lysosomes
- Structure
- Compartments/vessels
for waste disposal and
recycling.
- Function
- Digests and
recycles
materials.
- Cell junctions
- Structure
- Sites of physical contact
between cells.
- Function
- Connect
cells to other
cells and the
environment.
- Nucleus
- Structure
- An organelle with
a double
membrane.
- Function
- Houses the
genetic
information
of the cell.
(DNA)
- Nuclear envelope
- Structure
- Two lipid bilayers folded together in a
single membrane.
- Function
- Controlling which substances
can cross to the nucleus.
Basically the membrane of the
nucleus.
- Chloroplasts
- Function
- Organelle that
sparks
photosynthesis in
the cells of plants.
- Structure
- Oval or disc shaped plastids
specialized for
photosynthesis.
- Mitochondria
- Structure
- An oval shaped
organelle with a
double membrane.
- Function
- Eukaryotic
organelle that
specialises in
making ATP.
- Rough ER
- Structure
- Bound ribosomes.
- Function
- Transports carbohydrates
and proteins to different
parts of the cell
- Smooth ER
- Structure
- No bound ribosomes.
- Function
- Carries enzymes that
break down
carbohydrates, lipids,
toxins, and waste.
- Golgi Apparatus
- Structure
- Flat disks called cisternae.
- Function
- Modifies
proteins to
send them to
the ER.
- Ribosomes
- Structure
- Two subunits made of RNA and proteins.
- Function
- Organelle where
proteins are
synthesized
