This examination will cover Chapter 6 of the textbook Biology: Exploring Life by
Campbell, Williamson, & Heyden. The textbook is typical of a 9th grade academic biology class.
Chapter six is entitled “A Tour of the Cell”, which covers the general description of plant and
animal cells as well as how things transport inside and outside of the cell. The chapter goes into
detail covering what each organelle inside the cells does and the pathways that the molecules
follow in and out of the cell.
Instructional Objectives
 Ensure general understanding of chapter six
 Be able to recognize basic cell vocabulary
 Demonstrate an understating of the organelles of a cell
 Describe cell transport
 Be able to differentiate true and false facts
 Answer short answer questions with both words and pictures
For students with disabilities
The general idea of the exam will be the same. They will be tested a variety of ways, however, certain
questions will be modified and there will be less open ended questions for them to answer. Those that
are marked with an asterisk will be replaced with the matching question (such as 2b). The opened
ended questions that are marked with an asterisk will simply be omitted, as in most cases it is not that
students with learning disabilities are not intelligent, but simply need more time to process the
questions. Ideally, this would make the two tests equally challenging for both sets of students.
The questions with an asterisk should be supplemented with the questions located at the end of each
section for students with disabilities. All other questions will remain.

There are two types of endoplasmic reticulums.
Proteins are constructed in a cell by the ribosomes.
Golgi apparatus is an organelle that carries material in and out of the cell.
Chloroplast is the only organelle that once existed outside of the cell.
Cellular respiration occurs in the mitochondria inside a cell.
There is no genetic material located in the nucleus of a cell.
Lysosomes contain digestive enzymes that can break down other molecules.
There are two major classes of cells: prokaryotic and eukaryotic.
Chloroplast can be found in animal cells.
The only function of the membrane proteins is cell to cell communication.
Part C
Directions: Fill in the blank
(2 points each)
*16. The cell uses a process called exocystosis to move contents outside of the cell. The
reverse process is called __________________.
*17./*18. In osmosis, the cell needs to balance the concentration of water inside and outside
of the cell. When the concentration of the solute is greater it is called ______________. When
the concentration of the solute is lower it is called _________________.
*19. When a cell is undergoing active transport, it requires ______ to forced the pump to move
the molecules from low to high concentrations.
*20. _______________ is located inside the nucleus of a cell giving the cell its genetic
information.
* Questions from Part C will be replaced by additional questions from Part B for students with
learning disabilities.
Part D

2. Molecules spend the majority of their time in either a hypertonic or hypotonic situation.
This means they are constantly searching for equilibrium, so they are constantly moving. If a
cell reaches equilibrium to the point of stopping the cell has reached apoptosis (programmed
cell death).
