Cell Parts Worksheet – This is a high point assignment.
Name: __________________
Period: _________
Fill in the blanks on this sheet, and then draw each cell part on a separate piece of unlined paper. Draw neatly,
use color and label each part. The  symbol tells you what you must draw and label.
1. Robert Hook was famous for:
2. Matthias Schleiden:
3. Theodor Schwann
4. Rudolf Virchow
5. The three parts of Cell Theory are:
6. Organelles are:
7. The Plasma Membrane performs a number of critical functions for the ________. It consists of
a double layer of __________________. It regulates all that _____________ and leaves the
cell. In multicellular organisms it has markers on the outside surface so the organism can
recognize its own cells and identify ___________. Another name for the plasma membrane is
the cell membrane
 On a separate piece of paper, draw and label a large cell membrane that is approximately
the size of the whole sheet. You will be filling it with sketches of organelles so make it
big. In the corner of your paper, draw a close-up of section of the membrane showing the
phospholipid bilayer.
8. Nucleus contains ______________________ which are the instructions for making________.
The nuclear envelope is a double membrane surrounding the nucleus. It has many
_________________ for letting out genetic information. When the cell is making copies of itself,
the DNA is wound up in thick ropy strands called___________. When the cell is resting and
making ____________ the DNA is thin and relaxed and is called _____________. The large
solid spot is the _____________________ which manufactures
__________________________..
 Draw and label the nucleus and make sure it shows what it what it contains. Don’t forget
the nuclear pores.
9. Endoplasmic Reticulum (ER) is a network of double membranes found in the _____________
10. Rough E.R. is continuous with the __________________ and has ____________________
attached to it. This gives it its texture. These ribosomes manufacture ______________________
for the cell.
 Draw and label RER. Draw it continuous with the nuclear membrane. Remember to add
ribosomes to make it “rough”.
11. ______________ E.R. has no _______________. It acts as a ____________________system
throughout the cytoplasm. Its job is to ________________________ and
___________________________It also makes ___________________ for the cell.
 Draw and label SER inside your cell. Connect it to the rough E.R.
12. There are 2 kinds of ribosomes: The ________________ ribosomes are found in the RER and
make __________ that are shipped out of the cell. The ________________ ribosomes are
found in the cytoplasm. They make proteins that will be used:______________
 Draw a few of both kinds of ribosomes. Label one of each kind.
13. Golgi Body is responsible for _________________________ for the cell. It looks like stacks of
pita (pocket) bread. It is not connected to the E.R.
 Draw and label a Golgi body inside your cell
14. The peroxisomes’ function is to: _______________________________________
15. The lysosomes contain _______________ for digesting food particles. They have a double
membrane because it was originally part of the plasma membrane. They help protect you by
__________________ the bacteria that your white blood cells engulf. They also act as a
cleanup crew for the cell.
16. Vacuoles are used to hold ___________ and ______________
 Draw a food vacuole surrounded
by 3 lysosomes
17. Some single celled organisms contain a contractile vacuole whose function is to
____________________________
18. A mitochondrion is where the cell _________________________. It has a ________________
membrane. Mitochondria have their own ________ and manufacture some of their own
_______________.
Draw and label a mitochondrion inside your cell.
19. The cytoskeleton’s purpose is to __________________________ It is made if protein filaments
and tubes.
 Draw a few tubes and filaments inside the cytoplasm of your cell.
PLANT CELLS:
20. The large central water vacuole, found in plant cells, contains ___________ and gives the
plant cell structure. The tonoplast is a _______________ that surrounds the large water
vacuole.
 Your cell is a plant cell. Draw and label a large water vacuole inside the cytoplasm of your
cell. Label the tonoplast.
21. Outside the plasma membrane of a plant cell is the cell wall. In plants, it is made of the
polysaccharide ______________. In fungi, it is made of ____________.
22. Plasmodesmata are ____________________________ and they are used to ______________
______________________
 Draw a cell wall around the plasma membrane. Add some plasmodesma
23. Chloroplasts a kind of plastid that contain the pigment chlorophyll. They are the site of
______________________ which is where plants make food from _________ and __________.
Their color is _________________.
Draw and label a chloroplast inside your cell. Color it green.
Cell movement:
24. Some cells move with tiny oars called: ____________ draw 10 on this cell:
25. Others move by whipping one or two protein filaments called: _____________. Draw one on this
cell:
26. And others push out a pseudopod and fill it with cytoplasm. This structure is called
______________ movement. When the fluid in the cell fills the pseudopod, this is called
_________________________
Two types of cells:
27. All life on earth is either prokaryotic or eukaryotic. Prokaryotes are ancient. The contain DNA
and ribosomes but have no ____________________ or ____________________. Two
kingdoms of living things that are prokaryotes are the ______________ and the
________________
28. Eukaryotes have organelles and a nucleus. The four kingdoms that have eukaryotic cells are:
_________________ _______________ ____________ __________________
 Draw a prokaryote.
