Biology: CELLS UNIT REVIEW- 2014
This test will cover: Chapter 7 in textbook. The following questions provide an idea of the
subject matter that will be covered and provide a beginning to your studying.
Just because something is not on this sheet does not mean that it will not be on the test. Review
all your notes, lab papers, vocabulary list and quizzes to prepare.
1. What type of cell is shown below? ___________________
List 3 things present in this cell that helps you determine the type of cell it is:
1._______________________
2._______________________
3._______________________
2. Clearly and neatly DRAW an animal cell and add the following organelles:
Nucleus, Nucleolus, Smooth ER, Rough ER, Golgi Body, Mitochondria, Ribosomes,
Cell membrane, Centrioles (always a pair!), Lysosomes, Cytoplasm. Label each part!
3. What organelle is only found in animal cells? ________________
What is its function? __________________________________________
4. What cell parts are found in ALL cells (both eukaryotic and prokaryotic)
1. _________________
2. _________________
3. _________________
4. DNA
5. The three statements of cell theory:
1. All living things are made up of one or more ____________.
2. The cell is the smallest unit of ____________.
3. Cells come from existing ____________.
Name the three scientists that are responsible for providing some of the first evidence for
those ideas. _____________________, ____________________ & ___________________
6. What organelle or cell part is described?
Oval, produces ATP (energy), site of cellular respiration - __________________________
Oval, green, makes glucose, site of photosynthesis- _______________________________
Large, round, contains DNA, controls the cell, found in all eukaryotic cells- _____________
Smallest organelles, not membrane-bound, site of protein assembly from amino acids- _____
Largest organelle in plant cell, stores water and other substances- _________________
Network of tunnels that synthesize substances- _______________________
Found inside the nucleus, makes RNA (ribosomes are made of RNA) - _________________
Round, contains enzymes to break down substances within the cell- _________________
Semi-fluid substance containing chemicals for reactions taking place within the cell, the
organelles “float” in this - ________________________
Boundary of the cell, regulates what enters and leaves the cell, made of phospholipids and
proteins- ___________________
Rigid, outermost part of plant cell, contains cellulose- ____________________
Barrel shaped, always found in a pair, help with cell division- _____________________
7. Diffusion is the movement of substances from an area of __________ concentration to an
area of _________ _________________. Net flow of the substance will stop once an
___________________ is reached. A concentration ______________ is needed for diffusion
to occur.
8. Osmosis is the movement of ________ from an area of __________ concentration to an area
of _________ _________________.
9. In each diagram show the direction of net flow with an arrow ( see example):
Assume the membrane is semi-permeable (selectively permeable) and will allow water,
glucose and iodine to pass through but not starch or salt.

10. Which diagrams are showing the diffusion of a solute? _______________
11. Which diagrams are showing osmosis? _____________________
12. Label the parts of the prokaryotic cell:
13. Why do phospholipids orient
themselves into a
bilayer?__________________________
_
What part of the phospholipid is
hydrophobic?
______________________
5%
glucose
10%
glucose
e
E
14. Cell membranes are described by the ______________ mosaic model. This means the cell
membrane is made up of many different pieces and that they can move around and change
places!
15. Label the parts of the cell membrane and use the information on the diagram for questions
below:
16. Proteins in the cell membrane can function as receptors or __________ to move substances
from one side of the membrane to the other. This is known as _______________________
diffusion which is passive (does not require energy). If energy (ATP) is required to move a
substance it is known as _____________ transport.
17. Simple diffusion and facilitated diffusion require NO energy and therefore are considered
_______________________. Active transport does not require a concentration gradient;
molecules can move against a gradient and therefore _______________ must be used.
18. Cells can move in (or out) molecules through the cell membrane. However, larger particles
may require a different way of entering (or leaving) the cell. Define:
Endocytosis- __________________________________________________________
Exocytosis- ___________________________________________________________
BE SURE TO THOROUGHLY COMPLETE THIS,
STUDY IT and KNOW THIS INFORMATION FOR THE TEST.
ALSO KNOW Structure and Function information from your table!
Vocabulary list is posted on my webpage. However, we will cover the terms hypotonic,
isotonic, hypertonic, plasmolysis and turgor pressure in January when we return from
winter break!
