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.
Lysosomes
Function: digests and
recycles wast materials.
Structure: contains
acid hydrolase
enzymes that break
down waste
materials.
Described as the
stomach of the cell.
Cell Junctions
Function: Enable
communication
between cells.
Also reduce
stress placed
upon cells.
Structure: Consist
of multiprotein
complexes that
provide contact
between
neighboring 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.
Function: an
outer
membrane
that separates
the cell's
contents from
its
environment.
selectively permeable.
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.
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.
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.
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.
