| Organic | of, relating to, or derived from living matter |
| Carbohydrates | . any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. |
| Lipids | any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents |
| Proteins | any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms |
| Nucleic Acids | a complex organic substance present in living cells, esp. DNA or RNA, whose molecules consist of many nucleotides linked in a long chain. |
| Polymer | a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins. |
| monomer | a molecule that can be bonded to other identical molecules to form a polymer. |
| Condensation | the conversion of a vapor or gas to a liquid. |
| Dehydration Synthesis | a dehydration reaction is usually defined as a chemical reaction that involves the loss of water from the reacting molecule. |
| Hydrolysis | the chemical breakdown of a compound due to reaction with water. |
| Sexual reproduction | the production of new living organisms by combining genetic information from two individuals of different types (sexes) |
| Asexual reproduction | reproduction without the fusion of gametes |
| Double helix | a pair of parallel helices intertwined about a common axis, esp. that in the structure of the DNA molecule. |
| polar | having electrical or magnetic polarity. |
| diffusion | the spreading of something more widely. |
| Osmosis | a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. |
| Hypotonic | having reduced pressure or tone, in particular. |
| Hypertonic | having increased pressure or tone, in particular. |
| Istonic | (of muscle action) taking place with normal contraction |
