Cell Station Cards
Station #1 – Make your own
Flashcards
1. Each student should cut words and definitions
out
2. Match each word with the definition.
3. Check your results with those of your station
partners.
4. Glue together word and definition to make
flashcards.
5. Quiz each other based on the parts of the cell
and their functions if you have time remaining.
Station #2 - Cell Theory


1 – Watch the clip The Wacky History of Cell
Theory – Answer the questions on your worksheet.
(also on next slide)
Schleiden, Schwann, and Virchow Vow -- Cell Is the Basic Building Block of Life
Scientists Schleiden, Schwann, and Virchow have studied living organisms for several
years. With the help of the microscope they have determined that all living things are
made of cells. According to Matthias Schleiden and Theodor Schwann, these cells
seem to be the basic structural units within organisms. The two scientists also note
that the well-being of the organism depends on the well-being of its cells. Due to the
numerous and varied experiments and studies they have conducted, Schleiden and
Schwann are confident in their hypothesis and have laid out the points in what they
call the cell theory. Schleiden and Schwann have incorporated into the cell theory
experimental observations and conclusions of the famous scientist Rudolf Virchow,
who has observed that cells reproduce themselves.
Station #2 - Cell Theory

Some facts that may help you



Cell Theory:
 All living things are composed of cells
 Are basic units of living things.
 New cells arise only from preexisting cells.
Microscopes revealed the presence of cells and show their
detailed structure.
Animal and Plant cells contain organelles
 Organelles are “little organs”: small bodies that have a
specific structure and function
Station #3 Prokaryotic Cells vs. Eukaryotic Cell
1. Complete the questions on your worksheet based on the
information below
2. As you go through the organelle stations, complete the T chart –
see how much you can complete now.





Are extremely small
Do not have a nucleus
Have a cell wall with or
without peptidoglycan
Lack membrane bound
organelles
Bacteria are prokaryotic cells
Are larger cells
 There is a nucleus present
 Cellulose cell wall (plants only) or chitin
(fungi only)
 Contain many organelles
 Have larger ribosomes
 Everything except bacteria
Station #3 – Plant vs.
Animal
1. Fill in the blanks on your worksheet

Station #6 - Organelles
Complete the notes for
each organelle on your
worksheet
Lysosome - The Garbage
Storage Bin
Structure
 Round organelle surrounded by a
membrane
Function
 Contains digestive enzymes that
are used to
 Breakdown macromolecules into
small molecules the cell can use
 digest invading cells or to
destroy the cell if it needs to
be replaced (so it’s also called a
Suicide Bag!)
Vacuoles - Storage Tank
Structure
 Membrane enclosed sacs
for storage.
Function
 Stores materials such as
water, salts, proteins and
carbohydrates
Important Info
 Plant cells contain one
large central vacuole which
provides support in the
form of Turgor Pressure
Centrioles- the ushers
Structure
 Paired structures located
near nucleus
 Only visible when cell is
ready to divide
Function
 Helps organize cell division
Important Info
 Not found in plant cells
Mitochondria: The Powerhouse
Structure
 Usually oval, with a double
membrane
 Inner membrane (cristae)
within outer
membrane….inside is called
the matrix.
Function
 Site of respiration, where ATP is
made in both plants and animals
Important Info
 Found in large numbers in cells
requiring lots of energy.
 Powerhouse of the cell
Chloroplasts - The Bakery
Structure
 Small , flattened
structure found in plants.
 Surrounded by double
membrane; has inner
membranes inside
(thylakoid membranes)
 Contain chlorophyll
Function
 Site of photosynthesis
(Change light energy into glucose )
The Nucleus- The Brain of The Cell
Structure
 Large organelle
surrounded by a nuclear
membrane
 Contains pores
Functions
 Contains the DNA
(chromosomes) and
nucleolus
 Controls cell’s activities
 Nucleolus makes RNA
Ribosomes- The Factories
Structure
 Very small organelle
 Can be free floating
or can be attached
to the ER
Function
 Site where proteins
made (protein
synthesis)
Endoplasmic Reticulum (ER)
-The highway of the cell
Structure
 System of membranes
(channels and tubular
canals) enclosing a fluid
filled space
 Surface covered with
ribosomes
Function
 Transports proteins which
have been made in the
ribosomes
Smooth ER



No ribosomes
present
Makes and
transports lipids.
Detoxify drugs in
the liver.
& Rough ER




Ribosomes are
attached
Makes proteins for
the cell to export
Modifies the content
Forms vesicles then
carries contents to
the Golgi
The Golgi Apparatus - The UPS
Structure
 Group of smooth endoplasmic reticulum that have flattened sacs
 Vesicles are often seen at the edges
Functions
 Modifies, sorts and packages substances that are produced by
cells (mainly proteins and glycoproteins)
 Makes lysosomes
Cell Membrane : Gatekeeper of the Cell
Also called the plasma membrane
Structure
 Found on the surface of animal
cells and just inside cell wall of
plants
 Made of proteins and lipids
Functions
 Regulates what goes into and
out of the cell
 Also provides protection and
support
 Has receptor molecules to
respond to chemicals
Cell Wall: Supporter of Plant Cells
Structure
 A rigid structure that
surrounds plant cells.
 Made mainly of cellulose (a
carbohydrate)
Functions
 Supports and strengthens
plant cells
 Plant cells have a cell wall in
addition to a cell
membrane.
The Cytoskeleton- The Backbone
Structure
 Supporting structure
and transport system
 Network of protein
filaments
Function
 Helps the cell to keep
it’s shape
 Also helps cell move
using things called
microfilaments and
microtubules
