AP Bio Lab 3 Requirements (95 pts.)
General Expectations
It is expected that all graphs will be constructed according to the guidelines in the Appendix of the AP
Biology Student Lab Manual. Graphs must be neat and drawn with a ruler if done by hand. If you are
missing any of the required elements of a graph will lose an automatic 3 points for each missing
element (title, key, label and/or unit on the axes, etc). All tables must be made with a ruler if done by
hand. All tables must contain a title, labels for each column and units is necessary. All questions must
be answered in complete sentences and must be HAND WRITTEN. If I can’t easily read your writing
you will earn a zero for the section. Label the sections. Put them in the order in which they are given.
Mitosis Questions (5 pts each) – 15 pts
1. Explain the activities and control points of interphase
2. Compare and contrast mitosis in plant and animal cells.
3. What is the role of centrioles and the centrosome in mitosis?
Create Table 3.1 –3.1 pts
Follow the instructions in the Student Lab Manual. You must count three fields of cells.
Create the table with a ruler and make it as neat as possible.
Onion Cell Extension Question—15 pts
Assuming the onion roots you viewed were grown by submerging the roots in water, design an
experiment that would test the effect of changing the growing conditions on the growth of the roots.
You must include a control in your design, keep all factors constant except the tested variable, and
discuss how you will quantitatively measure your data. Be sure that you also include a hypothesis for
your proposed design with justification as to why that is the expected result. If you are missing the
hypothesis with logical, scientific justification it is an automatic -10 points.
