CELL PARTS NOTES
For this assignment, you will be reading your textbook and looking for information
dealing with parts of the cell. Remember that reading for a class is different from reading
for pleasure. For this assignment you are reading for specific details. So, please read the
pages carefully.
CELL PARTS
The information found in this packet deals with the parts of the cell. Another name for
cell parts is _______________________________________. Their function is to ______
________________________________________________________________________
CELL WALL
1. This part is only found in _________________________________ cells.
2. Give the three functions mentioned. (Be careful!)
a. __________________________________________________________________
b. __________________________________________________________________
c. __________________________________________________________________
3. What structure is this similar to in animals? (Think!)
________________________________________________________________________
4. What is the name of the nonliving material that makes up the cell wall? ____________
CELL MEMBRANE
1. Tell if the cell membrane is found around the outside of the following cells. If not, tell
what is.

Animal ___________________________________________________________

Plant _____________________________________________________________
1
2. List the three functions (jobs) given. (Look carefully!!)

__________________________________________________________________

__________________________________________________________________
3. Everything that the cell needs (including ___________________________ and
________________________) enters through the cell membrane. Harmful
___________________ __________________ exit. This allows the cell to maintain a
stable internal environment. Define stable. _____________________________________
________________________________________________________________________
NUCLEUS
1. Describe the nucleus.____________________________________________________
_______________________________________________________________________
2. It is also called the ________________________ __________________________,
because it acts as the _____________________________ of the cell.
3. What does the nucleus control? ____________________________________________
________________________________________________________________________
CHROMATIN
1. Chromatin is strands of ___________________ _________________ inside of the
___________________________. They contain the instructions for ________________
_______________________________________________________________________.
2. The chromatin condenses to form chromosomes which are needed for cell division.
Both of these are important because they contain _______________________________.
(Look up the information on chromosomes in another section of your book to find the
answer. The answer is an abbreviation.)
2
3. Define mutation according to your glossary. __________________________________
________________________________________________________________________
________________________________________________________________________
Because of mutations in the chromatin or chromosomes, a new trait can develop.
NUCLEAR MEMBRANE(ENVELOPE)
1. This is a thin membrane that surrounds the ______________________ and separates it
from the rest of the cell.
2. Substances enter and leave the nucleus through tiny openings called
___________________________.
PROTOPLASM
1. Protoplasm is the jelly-like substance in the cell.
2. There are two types of protoplasm: cytoplasm and nucleoplasm.
CYTOPLASM
1. This is said to be a ____________________________ material, because it is a clear
_______________________________________.
2. It is found outside of the _________________________________, but inside of the
__________________________________________.
NUCLEOPLASM
1. This is found inside of the ________________________________________.
2. What part that is mentioned in this packet is found in the nucleoplasm?
_______________________________
MITOCHONDRIA
1. They are often called the “_____________________________” of the cell because of
their function. What is it? __________________________________________________
________________________________________________________________________
_______________________________________________________________________
2. What is their shape? _____________________________________________________
3
3. In what type of cell do you think that you would find a lot of mitochondria - bone or
muscle cells? Explain why. _________________________________________________
________________________________________________________________________
________________________________________________________________________
GOLGI APARATUS
1. Receives the ___________________ from the endoplasmic reticulum, and
______________ to distribute them to other parts of the cell or _____________ the cell.
2. Give a description of the cell
__________________________________________________________.
3. Thought of as the cell’s ________________________.
VACUOLE
1. Give a description of a vacuole. ____________________________________________
________________________________________________________________________
2. The book says that most plant cells have _____________________________________
vacuole. It also says that some animal cells do not have vacuoles, while others do. What
size do you think the size of animal cell vacuoles would be? _______________________
3. Vacuoles deal with _________________________________. They can store either
substances needed by the cell, such as ___________________________________ and
_____________________________________, or they can store
__________________________________.
CENTRIOLE
1. Found only in animal cells, these paired organelles are typically located together near
the nucleus.
2. They deal with the cell cycle which is also called cell division or mitosis.
CHLOROPLASTS
1. These are found typically in _________________________________ cells.
2. The chloroplast captures the energy of the __________________________________
and uses it to make ____________________________ for the plant.
4
3. They are _________________________________ in color, because they contain
chlorophyll.
4. Chlorophyll is not discussed in this section of the book. Tell me how you are going to
find out where it is in the book. _____________________________________________
________________________________________________________________________
________________________________________________________________________
Based on the information in the other chapter, what process does chlorophyll deal with?
_______________________________________________
5. In which parts of the plant do you think cells with chloroplasts are located? _________
________________________________________________________________________
Therefore, in what parts of the plant do you think food is made? ____________________
________________________________________________________________________
Lyosomes
1. What type of cells would you find lysosomes? ________________________________
2. What are the functions of the lysosomes?


3. Lysosomes could be referred to as the cell’s _________________________________.
SPECIALIZED CELLS
1. Plant and animals are multi-cellular because they contain _____________________
cells.
2. In multi-cellular organisms, the cells are often quite ____________________________
________________________________________________________________________
and are _________________________________________________________________
_______________________________________________________________________.
5
3. In these organisms, the cells are often organized into tissues, organs, and organ
systems. Define the following---
cells _____________________________________________________________
_________________________________________________________________
