Molecule – Two or more atoms held together by covalent bonds.
glycolysis – the breakdown of glucose to pyruvic acid during cellular respiration
nucleotide – phosphate, sugar, base (building block of DNA)
tropism – A growth response that results in the curvature of whole plant organs toward or away from stimuli owing to differential rates of cell elongation.
prophase

10.2 – First and longest phase of mitosis
– the chromosomes become visible
– the centrioles separate
– a spindle begins to form
– the nuclear envelope breaks down

Isomers – organic compounds with the same molecular formula but different structure and therefore different properties. The 3 types are structural isomers, geometric isomers and enantiomers.
green alga – A member of a group of photosynthetic protists that includes chlorophytes and charophyceans, the closest living relatives of land plants. Green algae include unicellular, colonial, and multicellular species.
adaptive radiation – relatively rapid proliferation from an ancestral type into new types which fill a diversity of ecological niches
