Cell Biology and structure
- Endoplasmic reticulum
- Structure: Two kinds of
ER are the rough and
the smooth. Thousands
of ribosomes
transiently attached to
the outer surface of the
rough ER.
- Function: ER
forms a
continuous
compartment that
folds into
flattened sacs
and tubes.

of ribosomes
transiently attached to

- Golgi Apparatus
- Function: Finishes,
sorts, ships, liquids,
enzymes, proteins,
and modifies
polypeptide chains.
- Structure: Sac like
structures, that are
specifically used to
transport and ship
liquids an proteins.

- Chloroplasts
- Function: Specializes in
photosynthesis to
produce energy.
- Structure: Double
membrane bound
organelles. The inner
structure is called the
stroma which
contains many small
thykaloids. This is the
site of
photosynthesis.

- Mitochondria
- Function: Energy powerhouse;
produces many ATP by aerobic
respiration.
- Structure:
Dynamic skeleton
of proteins.
- Function: Energy powerhouse;
produces many ATP by aerobic
respiration.
- Lysosomes
- Function: digests and
recycles wast materials.
- Structure: contains
acid hydrolase
enzymes that break
down waste
materials.
Described as the
stomach of the cell.
- Function: digests and
recycles wast materials.
- Cell Junctions
- Function: Enable
communication
between cells.
Also reduce
stress placed
upon cells.
- Structure: Consist
of multiprotein
complexes that
provide contact
between
neighboring cells.
- Function: Enable
communication
between cells.
Also reduce
stress placed
upon cells.
- Plasma Membrane
- Structure:
Phospholipids
are the most
abundant lipid
in the cell
membrane.
- Many
different
proteins
embedded in
a bilayer or
attached to
one of its
surfaces carry
out membrane
functions.
- Many

- Function: an
outer
membrane
that separates
the cell's
contents from
its
environment.
- selectively permeable.
- selectively permeable.
- Structure:
Phospholipids
are the most
abundant lipid
in the cell
membrane.
- Microtubules
- Function: Involved in
nucleic and cell
division, organization
of intra cellular
structure, and intra
cellular trnasport, as
well as cilia and
flagella motility.
- Structure: made of
sub- units called
tubulin. Thick
strong spirals of
thousands of sub-
units.
- Function: Involved in
nucleic and cell
division, organization
of intra cellular
structure, and intra
cellular trnasport, as
well as cilia and
flagella motility.
- Microfilaments
- Function: assist
with cell
movement, its
particles produce
muscle movements
and contractions.
- Structure: Long, thin and stringy proteins. Made
of actin, which is the substance that induces
muscle movement and contractions.
- Function: assist
with cell
movement, its
particles produce
muscle movements
and contractions.
- Nucleus
- Function: The
nucleus provides
a site for genetic
transcription and
controls gene
expression.
- Structure: Largest cellular
organelle in animal cells.
The nucleus is protected by
an outter core called the
nuclear envelope and
inside it has the control
center called the nucleolus.
- Function: The
nucleus provides
a site for genetic
transcription and
controls gene
expression.
- Nuclear Envelope
- Function:
gateways
for
molecules
to enter
and exit
the
nucleus.
- Structure: consists of
two lipid bi-layers
folded together into a
single membrane.
Membrane proteins
embedded in the two
lipid bilayers aggregate
into thousands of tiny
pores thta span the
nuclear envelope.
