8th edition: Chapters 6,7, 11, 12
2.a.1 All living systems require constant input of free energy.
2.a.3 Organisms must exchange matter with the environment to grow, reproduce, and maintain organization.
2.b.1 Cell membranes are selectively permeable due to their structure.
2.b.2 Growth and dynamic homeostasis are maintained by the constant movement of molecules across membranes.
2.b.3 Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.
3.B.2 A variety of intercellular and intracellular signal transmissions mediate gene expression.
3.D.1 Cell communication processes share common features that reflect a shared evolutionary history.
3.D.2 Cells communicate with each other through direct contact with other cells or from a distance via chemical
3.D.3. Signal transduction pathways link signal reception with cellular response.
3.D.4. Changes in signal transduction pathways can alter cellular response.
4.A.2: The structure and function of subcellular components, and their interactions, provide essential cellular
4.B.1: Interactions between molecules affect their structure and function.
4.B.2: Cooperative interactions within organisms promote efficiency in the use of energy and matter.
Microscopy [C8] from Perry and Morton
o Goal: To properly use and care for a compound light microscope, to make a wet mount
slide, to distinguish between the utility of different types of microscopes (wet lab)
Structure and Function of Living Cells [C8] from Perry and Morton
o Goal: To identify cell parts visible with the compound light microscope, to note
similarities and differences between plant and animal cells, to note similarities and
differences between prokaryotic and eukaryotic cells (wet lab)
AP Biology Laboratory 1: Diffusion and Osmosis [C8] [C4]
o Goal: To investigate diffusion and osmosis using dialysis tubing; to relate particle size
and membrane properties, to determine the effects of concentration on diffusion using
dialysis tubing and potato cores (wet lab)
AP® Biology Laboratory 3 (Exercise 3A): Mitosis [C8]
o Goal: To observe mitotic figures in a student-made onion root tip slide, to compare and
contrast animals and plant cell mitosis by observing prepared slides, to determine the
time spent in each phase of mitosis by tallying cells in each phase in prepared onion root
tip slides (wet lab)
