Common misconceptions:
o Evolution always results in new species. 17.2
o Non-genetic traits can be passed to offspring. 17.2
o Genetic traits can be acquired when needed or lost when not needed. 17.1
o Evolution happens to an individual. 17.2
o Individual organisms choose to evolve. 17.3
o Variation is a response to selection pressure. 17.1
o The “strongest” organisms survive. 16.3
Quarter 4: Cells
Sub-Topics:
Cell structure and function
Eukaryotic cells and prokaryotic cells 7.1.
Structure, function and interrelatedness of cell organelles 7.2
Cellular processes
Characteristics of life regulated by cellular processes 7.3
Cell Transport (Diffusion and Active Transport)
Photosynthesis, chemosynthesis, cellular respiration 8.1, 8.2, 8.3 (Factors Affecting Photosynthesis), 9.1, 9.3
Cell division and differentiation 10.1, 10.2, 10.3, 10.4
Common misconceptions:
o Plant cells only produce oxygen.
o Only animal cells perform cellular respiration.
o Most of plants mass is from water or soil (gases have no mass).
o Oxygen is produced from the carbon dioxide in photosynthesis.
o Energy can be created by cellular processes.
o Molecules can only move downward.
o Equilibrium means no movement of molecules.
o Prokaryotic cells lack membranes.
o Only plant cells have cell walls.
o Plants are prokaryotic and animals are eukaryotic.
o All lipids are “bad.”
