Transcript
Happy Tuesday, BIO-NINJAS
What you need: Writing Utensil, Bellwork Sheet, Journal
and virus worksheets.
Have Homework out. (Video Notes)
Bellwork Today: Write and answer the question
below:
How are viruses different than bacteria?
Explain in 20 words or more. 
*Hint: use your homework notes. Also, remember that bacteria are
cells. Also think about vaccines vs antibiotics
Do the following in Pencil!!
1.Mark all viruses with a “V”.
2.Mark all bacteria with a “B”.
3.Label all of the DNA (genetic material).
4.Label the lipid envelope (if it has one).
5.Label the spikes (glycoproteins) if present.
6.Label the protein capsid.
Once you are sure you’ve labeled this correctly you may do the
following. You will have 10 minutes.
1.Circle all the viruses with a red color.
2.Circle all the bacteria with a blue color.
3.Color all of the DNA with a green color.
4.Color the lipid envelope of any virus with an
orange color.
5.Color any spikes (glycoproteins) in purple.
6.Trace any protein capsid brown.
Fold the document in half and
glue into your journal (left side)
You have 2 minutes
On the opposite page of your
journal write “Review Questions”
1. Which of the following are viruses?
A.
C.
B.
D.
2. A tomato plant in a greenhouse was found to be
infected with tobacco mosaic virus. A few weeks
later, nearby plants were also found to be infected
with the virus. Which of the following best describes
how the virus reproduced?
A. The virus made its own spores.
B. The virus produced seeds in the tomatoes.
C. The virus used the host plant’s resources
and machinery to reproduce.
D. The virus immediately killed the host plant and was
free to reproduce.

3. Is the population pictured above of a
bacterial or viral population? Explain.
4. Viruses are able to infect cells because they
share a common genetic code and are able to use
host cell enzymes to carry out protein synthesis.
There are some structures which are unique to
viruses and not found in cells. These include:
I. Protein capsid
II. Nucleic acids
III. Cell wall
A I only
B II only
C I and II only
D II and III only

5. Which viral reproduction cycle is pictured
above? Explain how you know.
Lysogenic: In this cycle the viral DNA is “integrated”
into cells existing DNA and “waits”
6. Scientists are designing new medicines to
fight infectious diseases caused by viruses.
One of the most effective ways these
medicines could limit the spread of the virus
within the body would be to —
A) prevent viruses from dividing
B) burst cells infected with viruses
C) stop viruses from attaching to cells
D) make it easier for viruses to leave cells
