Introduction to Cells- Stations Lab
Station 1: Microscopes allow scientists to study cells.
Microscopes:
How do light microscopes differ from electron microscopes? (How does each work? How much
can each magnify a specimen?)
Complete the chart below:
Pros Cons
Light Microscope
Electron Microscope
Cell Theory:
What are the three parts of the cell theory?
Levels of Organization:
Arrange the puzzle at your station to explain the five levels of organization. (The levels should
progress from smallest to largest.) Have your teacher initial here that your puzzle is correctly
arranged.

Station 2: Prokaryotic vs. eukaryotic cells
What are the basic features of ALL cells?

While all cells share the four features above, prokaryotes and eukaryotes differ in several major
ways. Complete the chart below to illustrate these differences.
Prokaryotes Eukaryotes
Nucleus? Yes / No Yes / No
Where is DNA found?
Membrane-bound organelles? Yes / No Yes / No
Average size of cells
Organisms with each type of cell
Label the following cells as either eukaryotic or prokaryotic
Cell Specialization:
How can cells be specialized to perform different functions? Provide specific examples.

The cell membrane controls passage of materials in and out of the cell
network of fibers that organizes structures in the cell.
Cell Membrane:
What other names do we use to refer to the cell membrane?
In your own word, what does selective permeability

Why do cells have to be so small?
Cytoskeleton:
What is the cytoskeleton made of?
What three functions does the cytoskeleton help with?
How are cilia and flagella similar? How do they differ?

What part of the cytoskeleton functions in cell division?
How do cytoplasm and cytosol differ?
Eukaryotic cells’ genetic instructions are stored in the nucleus and carried out
Nucleus:

• Nucleus-
• Nuclear envelope-
• Nuclear pores-
• Chromatin-
• Nucleolus-
Ribosomes:
What are ribosomes made of?
What do ribosomes do?
Where can ribosomes be found?
The endomembrane system regulates protein traffic through the cell.
Endoplasmic reticulum:
What is the endoplasmic retitculum (ER)?
How do rough and smooth ER differ in appearance and
function?

Golgi apparatus:
What are the main jobs of the Golgi apparatus?
(From the Golgi apparatus, vacuoles pinch off and carry materials to their appropriate
destination…)
Vacuoles:
What is a vacuole?
What kinds of substances can vacuoles hold?
How do vacuoles differ in plant and animal cells?
In you own words, summarize how the endomembrane system moves proteins through the cell.
(Some pockets that break off from the Golgi apparatus can be highly specialized…)
Lysosomes:
What are lysosomes and how do they help the cell
maintains homeostasis?
Why do you think it’s so important that lysosomes are
enclosed by membranes?
Station 6:
Mitochondria and chloroplasts change energy from one form to another.
Use the chart below to describe mitochondria and chloroplasts:

Structures surrounding cells help provide structure and support.
What structure surrounds plant, fungal, and algae cells?
What are animal cells surrounded by?
Overview: All cells share some basic properties, but prokaryotes lack internal structures bound
by membranes. While plant and animal cells are both eukaryotic and have many structures in
common, some structures are unique to different types of cells. Use checkmarks in the following
chart to describe the structures found in different types of cells.
