| cell membrane | selectively permeable outer boundary of a cell consisting of a phospholipid bilayer embedded with proteins; plasma membrane or cytoplasmic membrane |
| centrosome | cellular organelle consisting of two centrioles |
| chromosome | rod-like structure that condenses from chromatin in a cell's nucleus during mitosis |
| cytoplasm | contents of a cell, excluding the nucleus and cell membrane |
| cytoskeleton | A microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence. |
| differentiation | cell specialization due to differential gene expression |
| diffusion | random movement of molecules from a higher concentration toward one of lower concentration |
| endocytosis | process by which a cell membrane envelopes a substance and draws it into the cell in a vesicle |
| endoplasmic reticulum | organelle composed of a system of concentrated membranous tubules and vesicles along which protein is synthesized |
| equilibrium | state of balance between two opposing forces |
| exocytosis | transport of substances out of a cell in vesicles |

| filtration | movement of material across a membrane as a result of hydrostatic pressure |
| Golgi apparatus | an organelle that prepares cellular products for secretion |
| lysosome | organelle that contains digestive enzymes |
| mitochondrion | organelle that houses exzymes to catalyze reactions of aerobic respiration |

| anticodon | three contiguous nucleotides of a transfer rna molecule that are complementary to a specific mrna codon |
| codon | set of three nucleotides of a messenger rna molecule corresponding to a particular amino acid |
| dehydration synthesis | anabolic process that joins small molecules by releasing the equivalent of a water molecule synthesis |
| gene | portion of dna that encodes info to synthesize a protein a control sequence or trna of rrna the unit of inheritance |
| hydrolysis | enzymatically adding water molecule to split a molecule into smaller portions |
| oxidation | process which oxygen combines with another chemical the removal of hydrogen or the loss of electrons, opposite of reduction |
| replication | reproduction of exact dna molecule |
| substrate | substance which an enzyme acts upon |
