SCIENCE SNACK
Describe the
function of the cell
membrane.
Today’s Agenda:

You and your partner will be creating a
one-pager for your assigned organelle.

Your one pager should include
information in all four quadrants. We will
be presenting these in jigsaw format.

When you are finished with your onepager you may begin working on your cell
coloring page.
One Pager
Illustration
Function/Definition
Needs to be large enough for
everyone to see
Should be written in your own
words.
Name of
Organelle
Location
In what type of cell will you find this
organelle?
Create an Analogy
This organelle is like….. Because …..
Cell Terms Matching

To help you review your cell terms, match
the words with the appropriate definition.

When you are finished, you may continue
working on your cell coloring page.
Unicellular

having or consisting of a single cell
Multicellular
having or consisting of more than one cell
 Are multicellular organisms made up of
prokaryotic or eukaryotic cells?

Eukaryote

advanced cell type with a nuclear
membrane surrounding genetic material
and numerous membrane-bound
organelles dispersed in a complex cellular
structure
Prokaryote
primitive cell type that lacks a nuclear
membrane and membrane-bound
organelles
 What kind of organisms have prokaryotic
cells?

Animal Cell
A cell whose outside covering is a cell
membrane. This cell does not contain
chloroplasts, but contains other
membrane bound organelles.
 Prokaryotic or
Eukaryotic?

Bacterial Cell
This cell is covered by a cell wall, but does
not contain a nucleus or any other
membrane bound organelles.
 Prokaryotic or

Eukaryotic?
Plant Cell
a cell that contains a cell wall and
chloroplast. This is where photosynthesis
takes place.
 Standards Check:
Name one difference
between a plant and
animal cell.

Organelle

a differentiated structure within a cell,
such as a mitochondrion, vacuole, or
chloroplast which performs a specific
function
What does it mean to say that an
organelle is “membrane bound?”
 Give an example of a membrane bound
organelle.

Cell Wall

multi-layered, sturdy structure composed
of cellulose that provides plants and other
organisms with their rigidity
Plants have cell walls.
Do plants have
cell membranes?

Chloroplasts

membrane-bound organelles containing
chlorophyll that is found in
photosynthetic organisms

What process
occurs in
chloroplasts?
Chlorophyll

the green material found in chloroplasts
that is active in photosynthesis
Cytoskeleton

network of microtubules that support and
give structure to cell while aiding in
intracellular transport
Endoplasmic Reticulum

Carry proteins and other materials from
one part of the cell to another. The
smooth type of this organelle does not
contain ribosomes. The rough has
ribsomes attached.
Golgi Apparatus

multi-layered organelle near the nucleus
used for packaging of materials to be
transported out of the cell

What is another
name for the
golgi apparatus?
Lysosomes

the digestive plants of food for the cell,
changes shape from task to task
Mitochondria

genetically independent organelles that
produce energy for the cells along their
many internal folds, called cristae

What does “genetically
independent” mean?
Nucleus

spherical organelle that is the cell's
control center
Ribosome

extremely small grain-like organelle that
provides the sites for protein synthesis
(they may be free in the cytoplasm or
attached to the endoplasmic reticulum)
Vacuole

membrane-bound organelles in the
cytoplasm that are used for storage and
digestion

What is a
plant like when
its vacuoles
start to empty?
Cell Membrane

semi-permeable membrane that
surrounds the cell’s cytoplasm. This is
what controls what goes in and out of the
cell
Define
Semi-permeable.

Nucleolus

a small, typically round granular body
composed of protein and RNA in the
nucleus of a cell
Nuclear Membrane

the double-layered membrane enclosing
the nucleus of a cell. Contains pores
which allow materials to pass in and out
of the nucleus (such as RNA)
Chromosomes

the microscopically visible carriers of the
genetic material. They are composed of
deoxyribonucleic acid (DNA) and
proteins. Humans have 23 pairs.
Cytoplasm

the gel-like substance in cells. This is
where organelles are found.

Animal Cell (human cheek cell)
Guess the Cell
Plant Cell (Elodea)
 Standards Check: What is the function of
the green organelle found in these cells?

Guess the Cell
Plant Cell (Potato)
 What is the large purple spot in the cell?
 Why are potato cells not GREEN?

This was taken with a
compound light
microscope.
The purple color is due
to a violet stain.
Guess the Organelle

Golgi Apparatus
Golgi Apparatus of
Rabbit Epididymus- it is
not clear why the Golgi
is exceptional in these
epididymal cells.
The Golgi apparatus are
the large, circular
structures
This was taken with an
electron microscope.


Lysosomes
Group of lysosomes
found in liver tissue.
You can also see
Mitochondria, Rough
ER, and the cell
membrane in this
photo.

and free (RiF)
