Explain the three parts of the cell theory.
 Matthias Schleiden, Botanist, 1837
All plants are made of cells.
Explain the three parts of the cell theory.
 Theodor Schwann, Physiologist, 1838
All animals are made of cells
Explain the three parts of the cell theory.
 Rudolf Virchow, 1858
All cells are made from the division
of existing cells
How well did you remember the cell
theory?
A. I remembered and
understood all of the cell
theory.
B. I had to correct one part of
the cell theory.
C. I had to correct two or
more parts of the cell
theory.
D. I couldn’t remember any of
the cell theory.
Correctly use a compound light microscope
to observe plant and animal cells.
• List the 4 types of microscopes.
• Describe the steps, in order, for using a
compound light microscope.
Correctly use a compound light microscope
to observe plant and animal cells.
• List the 4 types of microscopes.
Compound Light - 40x-400x, Living Specimens, 2D
Dissecting – 3x – 10x, Living Specimens, 3D
Transmission Electron - 500,000x, Dead, 2D
Scanning Electron – 30,000x, Dead, 3D
Correctly use a compound light microscope
to observe plant and animal cells.
• Describe the steps, in order, for using a compound
light microscope.
• Double check for scanning power
• Place the slide on stage
• Find what you’re looking for and focus with course
adjustment. Center the specimen.
• Switch to low power and focus with fine adjustment.
Center the specimen.
• Switch to high power and focus with fine adjustment.
How well did you remember the parts
of the microscope learning goal?
A. I knew all four types of
microscopes and how to use it
properly.

microscopes and but not how
to use it properly.
C. I did not know all four types of
microscopes but I did know
how to use it properly.
D. I could only remember parts of
this learning goal.
Explain individual function and
interrelatedness of organelles.
In the human body, organs perform
specialized jobs. For example, the heart
transports blood. In cells, tiny ___________
carry out specialized jobs.

Animals and plants are always multicellular with specialized
(they look different & function differently) cells.
Cell walls protect cells from bursting and provide them
support against pressure (so they don’t get crushed).
