EOC Prep:
Multiple choice
1. Chloroplasts are important organelles because they
A. are necessary to release stored energy
B. store wastes in both plants and animals
C. use energy from the sun to make food
D. are in the nuclei of plant and animal cells

these cells require a large amount of energy to maintain their activity. The
organelles that are most directly involved in releasing this energy are the
A. vacuoles
B. chloroplasts
C. ribosomes
D. mitochondria

Open-ended questions
1. A newly discovered disease called BCITalitis causes an abnormally high pH in the
lysosomes. Explain why this would prevent lysosomes from performing its function
and how this could be harmful for the cell.

2. Suppose a cell could not properly form all the macromolecules necessary to
generate the cell membrane. Which macromolecules absence would affect the
function of the cell membrane the most? Explain why this macromolecule is
important for proper cell membrane function.

3. Below are pictures of 2 cells. Suppose that these cells were in two different
patients that had a disease affecting their endoplasmic reticulum. In order for the
patients to survive, a liquid medicine must travel by diffusion from the outside of
the cell to the inside of the cell to get to the endoplasmic reticulum quickly. Which
cell type would be better for the patients to have in order to be cured? Why?

5. A scientist discovers a new plant species, Uncommunlias staris. While observing
this plant’s cells under the microscope, the scientist notices that the cells from the
roots look different compared to the cells from the leaves. The root cells had large
vacuoles, long hair like projections and no chloroplasts. The leaf cells also have a
vacuole, have no hair like projections have many chloroplasts. Why might the root
cells differ from the leaf cells? Be specific in your response and be sure to talk about
the functional role each cell type (root and leaf) might perform for the plant.

6. In 2007, a radio station held a “Hold Your Wee for a Wii” contest where whoever
can drink the most water without going to the bathroom wins a Nintendo Wii. One
of the contestants died of water intoxication, only hours after participating in the
contest. Based on what you know about osmosis and cell transport, explain why the
women died. Be sure to use the following terms in your response: osmosis,
hypotonic, hypertonic. Draw what the cells would look like under water intoxication
with arrows showing where the water is moving
