COLLEGEBOARD CONCEPT 3: Organisms are linked by lines of descent from common ancestry
In eukaryotes, conserved core elements provide evidence for evolution. These features include the presence of a cytoskeleton, a nucleus, membrane-bound organelles, linear chromosomes, and endomembrane systems.
In eukaryotes, the internal membranes partition the cell into specialized regions that allow cell processes to operate with optimal efficiency. Each compartment or membrane-bound organelle enables localization of chemical reactions.
Eukaryotic cells also maintain internal membranes that partition the cell into specialized regions so that cell processes can operate with optimal efficiency by increasing beneficial interactions, decreasing conflicting interactions and increasing surface area for chemical reactions to occur.
-membranes and membrane-bound organelles in eukaryotic cells localize (compartmentalize) intracellular metabolic
processes and specific enzymatic reactions.
-ER, mitochondria, chloroplasts, golgi, nuclear envelope
-Archea and Bacteria generally lack internal membranes and organelles and have a cell wall
Each compartment or membrane-bound organelle localizes reactions, including energy transformation in mitochondria and production of proteins in rough ER.
Organisms have evolved various mechanisms for obtaining nutrients and getting rid of wastes, including osmoregulation.
-
SKILLS REQUIRED:
-explain how internal membranes and organelles contribute to cell functions
-describe specific examples of features shared by all domains or within one domain of life, and how these shared features support the concept of common ancestry for all organisms
-Use representations and models to describe the differences in prokaryotic and eukaryotic cells.
- "Surface area-to-volume ratios affect a biological system's ability to obtain necessary resources or eliminate waste products."
-examples: root hairs, cells of the alveoli, cells of the villi, microvilli

COLLEGEBOARD CONCEPT 2:
- "Internal membranes facilitate cellular processes by minimizing competing interactions and by increasing surface area where reactions can occur."
- "Membranes and membrane-bound organelles in eukaryotic cells compartmentalize intracellular metabolic processes and specific enzyme reactions." (ER, Mitochondria, Chloroplasts, Golgi, nuclear envelope)
- "Archea and Bacteria generally lack internal membranes and organelles and have a cell wall."
- Each compartment or membrane-bound organelle localizes reactions, including energy transformation in mitochondria and production of proteins in rough endoplasmic reticulum.
