| autotrophic nutrition | "self feeder"-manufacturing of organic food form inorganic materials |
| heterotrophic nutrition | "other"-obtaining pre-made organic food from other sources |
| autotrophs | self-feeders |
| "photo" synthesis | "light energy making" |
| "chemo"synthesis | "chemical energy making" |
| photosynthesis (process of) | the process during which light energy is converted into chemical energy-organic molecules |
| chloroplasts | organelle within which photosynthesis (photolysis) and carbon fixation reactions take place |
| chlorophyll | green pigment; protein molecule that absorbs specific wavelengths of light-essential to the process of photosynthesis |
| chromatography | technique used to separate and study the variety of pigments contained within the chloroplasts |
| spectrum | contains ROYGBIV; red,orange,yellow,green,blue,indigo and violet |
| stomates | small openings on the leaf that allow for the exchange of gas |
| petiole | attaches the leaf to the stem |
| guard cells | regulate the size of the stomates |
| cuticle | waxy covering on the leaf; prevents water loss |
| xylem | conducting tissue-movement of water |
| phloem | conducting tissue-movement of food and minerals |
| palisade mesophyll | located in the upper epidermis-most photosynthesis occurs here |
| spongy mesophyll | contains air spaces which are surrounded by moist surfaces;exhange and circulation of gas |
| epidermis | outer cell layer;protects from water loss, resistance to invasion of fungi and protection from physical injury |
| carbon fixation | also known as the dark reaction |
| PGAL | phosphoglyceraldehyde; stable moleculde found in photosynthesis and cellular respiration |
| coelenterate | animal phylum including Hydra which has a two-way digestive tract |
