1. The cell membrane is mainly composed of ________________ & ________________.
2. The framework consists of a double layer of _________________________________.
3. Water-soluble substances, such as glucose, amino acids, ions, and water need the help
of various ______________________________ for transport through the cell membrane.
4. The phospholipid bilayer has hydrophilic ___________________ that form the surface
and interior of the membrane, and hydrophobic ____________________ that face each
other.
5. Draw a simple diagram or the phospholipid bilayer and label the polar heads and the
nonpolar tails.
6. Fibrous _______________________ may span the length of the membrane and serve as
receptors for the cell.
7. One type of globular proteins form _______________ (which are holes) that allow
water to pass through the cell membrane.
8. Other integral __________________serve as channels and selectively transport ions for
the cell.
9. ______________________ proteins, found on the surface of the cell, may be enzymes
or glycoproteins that identify the cell.
10. ___________________________ molecules are embedded in animal cell membranes,
but not plant cell membranes.
11. ___________________________ helps to stabilize the membrane.
12. Complete the activity to match pictures of the cell membrane parts with the correct
label. You must drag the name over the picture. If you are correct, a blue box will appear
to let you know you made a match. After you matched them all, click “Next”.
13. Draw a simple picture of the part that forms the basic frame of the cell membrane.
14. Go to the following site: http://cellsalive.com/cells/3dcell.htm. Then click on the green
words “Take me to the ANIMATION” & Choose Animal Cell
15. The nucleolus is found in the _____________________ and produces
_______________________.
16. The nucleus is the most obvious organelle in any______________________________
cell. Within the nucleus is ___________, which provide genetic information.
17. The rough ER appears “pebbled” because of _______________________. These
ribosomes synthesize, or produce, _________________________. The endoplasmic
reticulum then provides ___________________________ throughout the cell for these
proteins.
18. The Golgi apparatus is a stack of membrane-bound vesicles that are important for
___________________________ macromolecules for transport throughout the cell.
19. The centrosome is an area where __________________________ are produced. The
centrosome is actually a pair of small organelles called ___________________________.
The centrioles are important for animal cell ________________________.
20. Microtubules and microfilaments are part of the ___________________________,
which helps maintain cell shape. The primary importance of the cytoskeleton is cell
_______________________, which means movement.
21. Lysosomes are common in _______________________ cells. They contain enzymes
for intracellular __________________________. Uncontrolled release of lysosome
contents into the cytoplasm can also cause cell necrosis, which means ________________.
22. Mitochondria produce the ___________________ a cell needs to move, divide,
produce products, and contract. Within cristae of the mitochondria, sugar is combined
with oxygen to produce __________, which is the primary energy source for a cell.
23. The cytosol is the “_____________” of the cell. __________________________ is a
collective term for the cytosol plus the organelles suspended in the cytosol.
24. Now click on the Plant Cell.
25. Plant cells have a rigid cell wall made of ______________________________. In
higher plants this polysaccharide is usually _____________________________. Fluid
that collects in a plant cell’s vacuole can push on the cell wall and create a pressure that is
responsible for the crispness in fresh___________________________.
26. Chloroplasts are found only in ____________________ cells. They contain
___________________, which is responsible for the plant’s green color. Within the
chloroplasts are membrane structures called thylakoids, which appear in stacks called
_____________________.
27. In _____________________ cells the vacuoles are generally small.
28. The vacuoles in plant cells tend to be _______________________. In the plant cell
the vacuole is responsible for ________________________ nutrients and waste products,
increasing cell size during _____________________, and even acting like the
________________________ of animal cells. A plant’s vacuole also regulates
__________________ pressure. If a plant does not have enough water, this pressure will
drop and the plant ____________________.
Use your notes to answer the following questions.
29. Which zoologist observed that the tissues of animal had cells? __________________
30. Which botanist first observed that plants contained cells? ______________________
31. Who was the first person to see cells while looking at cork cells? ________________
32. Who was the first to observe living cells in pond water and called them
“animalcules”? ___________________________________
33. Which 3 scientists came up with the basic components of the cell theory?
_______________________________________________________________________

1. ________________________________________________________________
2. _________________________________________________________________
3. _________________________________________________________________
35. Which type of cells do NOT contain a membrane bound nucleus? ________________
36. Plant and animal cells are __________________________ cells, which are more
advanced cells.
37. What are the 4 main parts of a eukaryotic cell?
1. _________________________________
2. _________________________________
3. _________________________________
4. _________________________________
38. A __________________________ is a long, whip-like structure (tail) of a cell that
aids in movement. ______________________ are tiny, hair-like projections that cover a
cell and aid in movement.
