AP Review Questions

Answers must be in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin to write.

Question 1
This question must be completed by September 16th

Many biological structures are composed of smaller units assembled into more complex structures having functions based on their structural organization. For THREE of the following complex structures, describe the smaller units, their assembly into the larger structures, and one major function of these larger, organized structures.
(a) A eukaryotic chromosome
(b) A mature angiosperm root
(c) A colony of bees
(d) An inner membrane of a mitochondrion
(e) An enzyme

Question 2 needs to be complete by October 17!

During an investigation of a freshwater lake, an AP Biology student discovers a previously unknown
microscopic organism. Further study shows that the unicellular organism is eukaryotic.
(a) Identify FOUR organelles that should be present in the eukaryotic organism and describe the function of
each organelle.
(b) Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must perform
many of the same functions as eukaryotes. For THREE of the organelles identified in part (a), explain how
prokaryotic cells carry out the associated functions.
(c) According to the endosymbiotic theory, some organelles are believed to have evolved through a symbiotic
relationship between eukaryotic and prokaryotic cells. Describe THREE observations that support the
endosymbiotic theory.

Questions #3

1. Membranes are essential components of all cells.

(a) Identify three macromolecules that are components of the
plasma membrane in a eukaryotic cell and discuss the struture and function of each.

(b) Explain how membranes participate in three of the following biological processes:
Muscle contraction
Fertilization of an egg
Chemiosmotic prodution of ATP
Intercellularr signaling
