Cell Theory
Cells = basic unit of struct
All cells arise fr. preexisting cells
All organisms made of cells
Emergence of Cell Bio
Biochemistry
Cellular func.
Genetics
Info flow + heredity (anything about DNA/genes)
Cytology
Cell struc+optical techniques (microscopes)
Theme
Structure tell func.
5 principles
Selectively permeable memb.
Insolvable in H2O
Water
Universal solvent
Polarity + H+ bonds
Cohesiveness
High b.p.; heat of vaporization; surface tension
Synthesis
Carbon
Backbone of all organisms
Bonding bet. Carbon atoms: covalent bonds = stability
Diverse -> 4 bonds
Form stereoisomers (mirror images): tetrahedral struct.
Self assembly
