I. Define:
Cell =
Unicellular =
Multi Cellular =
II. Cell Theory: What are the three parts of the Cell Theory?
1.
2.
3.

blank.
a.
b.
c.
d.
e.
f.
Cell Wall
Cytoskeleton

l.
Golgi Bodies
Cytoplasm
Lysosomes
Mitochondria
Nucleus
Ribosomes
______ 1. This is the protective layer of all cells. It acts like a screen on a window, letting some
things in the cell and some things out.
______ 2. This is a gelatin-like substance that flows inside the cell. All organelles float around in
this.
______ 3. This is the control center of the cell. This organelle directs all cell functions and
activities.
______ 4. Food-making organelles in plant cells. This organelle is the site of photosynthesis and
it also contains the green chemical pigment chlorophyll.
______ 5. Organelle responsible for producing and releasing energy. It does this by breaking
down food. Looks like a kidney bean.
______ 6. Small organelle that makes or manufactures proteins. Can float free or can be found
on the sides of endoplasmic reticulum.
______ 7. This organelle is responsible for transporting materials around the cell. It is
a folded structure near the nucleus and can extend all the way to the cell membrane.
______ 8. Organelle that sorts and packages proteins and other cellular substances.
______ 9. This organelle is for temporary storage of materials including water. Plant cells have
one that is very large for storing water. Part of its name in the plant cell is called “central”.
______10. This organelle breaks down and recycles old, worn-out cell parts. It is called the
“garbage man” of the cell. It contains powerful digestive enzymes.
______11. This organelle is found on the outside of plant cells outside of the cell membrane. It is a
rigid structure that gives plants the ability to stand up.
IV. Types of Cells: There are two types of cells: Eukaryotic and Prokaryotic. Fill in the blank with
either Eukaryotic or Prokaryotic to complete the sentence.
1. ________________ cells do not have membrane-bound (surrounded by a membrane)
organelles.
2. ________________ cells have membrane-bound (surrounded by a membrane)
organelles.
3. _________________ cells are the type found in the human body.
V. Microscope magnification: Find the total magnification of each microscope below.
1. Objective Lens = 40x
Eyepiece = 10x
Total Magnification = __________
2. Objective Lens = 5x
Eyepiece = 25x
Total Magnification = __________
3. Objective Lens = 20x
Eyepiece = 10x
Total Magnification = __________
VI. Essays: Answer each question or task below in complete sentences.
1. Explain the difference between chloroplasts and mitochondria. Include what they produce
and in what type of cells they are found.
2. What function do lysosomes provide for a cell and what might happen if they don’t work
correctly.
3. Explain the difference between Eukaryotic and Prokaryotic cells and give an example of
living things that have those types of cells.
