‘The Cell’ Recorded Lectures
Student Self-Evaluation
After listening and taking notes to the recorded lectures, quiz yourself. Make a
note of any topics you do not understand or want the instructor to review.
The Cell Recorded Lecture Part 1 (~21 min.):
1. List the three statements included in the Cell Theory.
2. List, in order, the levels of biological organization in the human body.
The Cell Recorded Lecture Part 2 (~25 min.):
1. Proteins that speed up the rate of chemical reactions are called
2. What are the three main components of the cell (plasma) membrane?
3. Proteins have three main functions in the plasma membrane. In general, what
are they?
1
4. Why are many chemical reactions performed at membranes?

cell as a whole are called
.
2. What organelle may be found on the surface of the ER or in the cytoplasm?
3. The building blocks of proteins are called
Many of these are bonded together to form a protein.
4. Organelles in the cell that are the sites of protein synthesis are called
.
5. What organelle is composed of protein rods and cylinders; they function in
movement & cell structure?
6. Which genetic disorder results in a loss of cellular functional shape due to a loss
of connections between the plasma membrane and the cytoskeleton? Red blood
cells balloon out and, therefore, have difficulty moving through small capillaries.

The Cell Recorded Lecture Part 4 (~26 mn.):

Chromosomes or
.
7. Each person obtains one member of each homologous pair from his/her
and one member from his/her
These are the maternal and paternal members of each homologous pair.
.
8. How many chromosomes did you get from your father?
9. How many chromosomes did you get from your mother?
10. What is the difference between the terms locus, gene, and allele?

11. How are homologous chromosomes alike?
12. How are homologous chromosomes different?
4
The Cell Recorded Lecture Part 5 (~22 min.):

.
2. How are the endoplasmic reticulum (ER) and the Golgi body alike?
3. How are the endoplasmic reticulum (ER) and the Golgi body different?
4. The term used for the DNA that is found in cells the majority of the time, when
the DNA is ‘active’ (proteins are being produced from the instructions in the
DNA), and, therefore, is less coiled? See the illustration of the uncoiling
chromosome in the Lecture Guide.
5. What form are the chromosomes found in only during the cell division process
and, therefore, are the most highly coiled (see illustration of the uncoiling
chromosome)?
5
The Cell Recorded Lecture Part 6 (~36 min.):
1. What organelle is affected by Tay Sachs and Pompe Disease? What specifically
is defective or missing in each of these diseases?
2. What organelle is used to acquire energy from glucose?
3. What organelle contains about 40 digestive enzymes?
4. Which genetic disorder results in an inability to break down glycogen in
lysosomes? It builds up in tissues and usually results in an early death.
5. Which genetic disorder results in blindness?
Why?
6. Explain why many researchers believe mitochondria were at one time singlecelled organisms (like bacteria) that were incorporated into and remained in a
larger cell.
7. From whom do you inherit your mitochondrial DNA (mtDNA)?
6
The Cell Recorded Lecture Part 7 (~45 min.):
1. Groups of similar cells performing similar functions are called the
2. Write the letter of the description with the appropriate tissue.
Muscle tissue
Nervous tissue
Epithelial tissue
Connective tissue
a.
b.
c.
d.
Examples are blood, fat, cartilage, and bone
Movement
Line the surfaces of the body
Sends electrical & chemical signals to
coordinate & control body activities
3. What genetic disorder results in a defective gene for dystrophin?
4. In order to form all of the different types of cells in the body, different genes are
turned on and off in different cells. This process of forming different types of cells
is called…
OR
5. The first cell formed after fertilization is called the
This is the ‘fertilized egg.
.
6. What does the sperm contribute to the first cell formed after fertilization?
7. What does the egg contribute to the first cell formed after fertilization?
7
8. What genetic disorder is lethal to males and results in a variety of symptoms for
females (such as marbled skin, vesicles that turn wart-like, loss of hair,
seizures…)?
9. What types of human cells do NOT have 46 chromosomes? Why?
10. Match the following letter to the appropriate term:
Multipotent
a. able to develop into any type of cell, including an
complete new organism
Totipotent
b. able to develop into many different types of cells
Pluripotent
c. able to develop only into a few different types of cells
Specialized
d. not able to develop into any other types of cells
11. Describe four different times when a gene might be expressed or ‘turned on’.
8
12. Describe the process which results in the specialization of cells and when this
occurs during development.
Questions concerning the ‘Organization of Cell Activities: Synthesis and
Modification of a Protein’
1. List the organelles described in the lecture that may be used to form a functional
protein. These organelles synthesize, alter and transport proteins so that they are
able to carry out their intended function for the cell/body. Make sure the
organelles are in the CORRECT ORDER.
9
2. What are the functions of the above organelles in the process to synthesize, alter
and transport proteins?
3. Describe why and how portions of membranes are able to ‘pinch off’.
