Cellular Organelles
Students will understand that
organelles have specific functions that
work together to sustain life…like
organs inside our bodies.
Review




Which type of cell (prokaryotic or
eukaryotic) contain membrane bound
organelles?
Which type of cell contains a nucleus?
Which type of cell was the first to
inhabit Earth?
Which organelles, discussed yesterday,
contain their own DNA and a double
membrane?
Plasma/Cell Membrane



outer boundary of
the cell
Composed of a
lipid bilayer.
Two layers of
phospholipids with
proteins
throughout.
Nucleus
Chromatin

Nucleolus



The center of
cellular activity.
Contains a porous
membrane.
Contains thin fibers
of DNA and protein
called Chromatin.
Contains a small
round nucleolus
which produces
ribosomes.
Mitochondrion



It contains two
membranes.
Contains its own
DNA.
Produces the
high energy
compound ATP.
Chloroplast
Thylakoid
Granum
Stroma



Contains a
double
membrane.
Found in plants
and algae.
Site of
photosynthesis!!
Ribosomes


Ribosome

They contain two
sub units.
The center of
protein synthesis.
They are either
free floating or
attached to the
Endoplasmic
Reticulum.
Endoplasmic Reticulum



Ribosome

A complex network of
transport channels.
Two types: Smooth and
Rough
The smooth is
ribosome free and
functions in poison
detoxification.
The rough contains
ribosomes and releases
newly made protein from
the cell.
Golgi Apparatus


A series of flattened
sacs that modifies,
packages, stores,
and transports
materials out of the
cell.
Works with the
ribosomes and
Endoplasmic
Reticulum.
Lysosomes



Contains a variety of enzymes.
Digests particles inside or outside the
cell.
They are instrumental in recycling
cellular debris.
Vacuole


Vacuole
(tonoplast)
Sacs that help
nutrient storage
and water
Chloroplast
balance.
Found mostly in
plants and protists.
Nucleus
Cell Membrane
Cell Wall
Cytoskeleton



Framework of the cell
Contains microfilaments and
microtubules.
They support the cell, giving it its
shape and help with organelle
movement.
Cell Wall


Plants, algae, fungi, and bacteria
contain an extra structure surrounding
its plasma membrane; animals DO
NOT
It is called a cell wall.
