Cytoskeleton
Acts as skeleton and
muscle
Provides shape and
structure
Helps move
organelles around the
cell
Made of three types of
filaments
Endoplasmic
Reticulum
A.k.a. “ER”
Connected to nuclear
membrane
Highway of the cell
Rough ER: studded
with ribosomes; it
makes proteins
Smooth ER: no
ribosomes; it makes
lipids
Ribosome
Site of protein
synthesis
Found attached to
rough ER or floating
free in cytosol
Produced in a part of
the nucleus called the
nucleolus
Golgi Apparatus
Looks like a stack of
plates
Stores, modifies and
packages proteins
Molecules transported
to and from the Golgi
by means of vesicles
Lysosomes
Garbage disposal
of the cell
Contain digestive
enzymes that
break down
wastes
Which organelles do
lysosomes work with?
Mitochondria
“Powerhouse of the
cell”
Cellular respiration
occurs here to release
energy for the cell to
use
Bound by a double
membrane
Has its own strand of
DNA
Vacuoles
Large central vacuole
usually in plant cells
Many smaller
vacuoles in animal
cells
Storage container for
water, food, enzymes,
wastes, pigments, etc.
What type of microscope may have
been used to take this picture?
Make it personal
Rank the 5 organelles, (1 being the most)
that you think are the MOST important to the
cell. Share your rankings with your group
mates, be sure to defend any differences
that arise.
It’s a metaphor…
Create, draw and color a metaphor for
the cell and all of the parts we went over
(cannot use my city example).

Question of the Day!
1.) What do you think contributes more to
someone’s personality, their cells or their
experiences?

Question of the Day!
My hypothesis was incorrect the nickel did not hold as many
drops as I thought; the coin that held the most drops was the
quarter. The quarter held on average 22 drops, while the
others held less.
-How can you rewrite this conclusion to make it better?

BREAKING NEWS!!!!
I received an anonymous letter yesterday
afternoon from presumably the killer.
The handwriting is consistent with that of
Jeff Miller. We have two questions to
solve:
1.) Where is the Miller family?
2.) What does the killer want from us?

Cell Organelles
Organelle= “little
organ”
Eukaryotic cells vs.
Prokaryotic
The liquid component
of the cytoplasm is
called cytosol
The stuff in between
organelles is called
cytoplasm
Cell Membrane
Boundary of the cell
Made of a phospholipid bilayer
Nucleus
Control center of the
cell
Contains DNA
Surrounded by a
double membrane
Usually the easiest
organelle to see under
a microscope
Usually one per cell
Contents of the Safe!
1.) A white mask (pictured on the
next slide.)
2.) The minister’s wallet and
phone.
3.) A packet of x-rays
4.) A very small journal.

These x rays are that of “Luke Brave”
Journal Entry
In my life I have two regrets. The first that
because of the web of lies and deceit that
have cost this world two lives.
I killed Kathleen……I killed Luke…I had no
choice, the angel of death had instructed me
to do I could not refuse….For this I must take
myself from this world….Goodbye….
