Section 4 – Outside Class Assignments
Thoughtfully answer each of the following questions or tasks. Include all your
reasoning and work wherever it seems appropriate. Type the question and
then the answer. Go in order. Due dates for each assignment will be given in
class. (Please remember - homework that is passed in late is automatically
discounted 15% and 0% after the unit test.)
1) Make a table with two columns. In the first column, list a contributor to
the modern cell theory. In the second column, list his/her contribution to
the theory.
2) Why are cyanobacteria so important to our planet and us? Provide three
specific facts and explain how these facts support life on our planet.
3) Bacteria are everywhere, even on us.
a) Draw (do not copy and paste someone else’s diagram) and label the
structures in a typical bacterium.
b) List three types of food bacteria use and the general names of those
types of bacteria.
c) What makes a bacteria “bad” or “good”?
4) The endosymbiotic theory had a profound effect on the theory of
evolution.
a) What is the endosymbiotic theory?
b) Why was it such a revolutionary idea?
c) Use the endosymbiotic theory to explain the evolution of plant cells.
5) Jack Szostak said “Life emerged from chemistry, then after that it’s just
details.” Explain his statement and then give an example of how this
statement might be true.
6) Consider a compound light microscope like the one used in class.
a) Explain why the field diameter for your compound microscope is wider
under a low power magnification and narrower under a high power
magnification.
b) Explain to your 7 year old cousin why an amoeba looks so big when
you look through a microscope but that it’s almost invisible to the
naked eye.
Cell Biology Introduction
7) Based on your lab work and reading, make a list of the properties all living things
exhibit. Did you observe these properties in all or only some of your protist
samples? Cite your evidence.
8) Based on your assigned reading and lab observations, explain how you think
paramecium, amoebas, euglena and stentors and Volvox move (locomote). Use
diagrams to clarify if necessary. Use lines to show a typical path for each
protist.
9) Make a sketch of your own or some other human’s digestive system (mouth,
throat, stomach, intestines, anus). Show where the food enters your or some
human’s body, gets digested, and leaves your body. Label all the involved organs.
Next to this sketch, draw a picture of a paramecium or amoeba or stentor or
tetrahymena you observed in class. Label the features involved in digestion and
show where the food enters, leaves and gets digested. How are you and the
single celled organism the same in this regard? How are you different?
Cell Biology Introduction
10) Although all of the species you observed in the protist lab exist in fresh water,
each has unique structures and behavior patterns that allow it to survive along
side the other protists. Each species is adapted to a specific niche in the pond.
For each species you observed in the lab, describe the niche in the pond where
it might best survive; i.e. out compete the other protists. Think about how it
gets its food, how it escapes its predators, what it eats, how it defends itself,
or whether it is plant like or animal like.
