photosynthesis | the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants,algae , and certain bacteria using energy from the sun. |
respiration | the act of respiring; inhalation and exhalation of air; breathing |
stomata | any of various small apertures, especially one of the minute orifices or slits in the epidermis of leaves, stems, etc., through which gases are exchanged. |
guard cells | either of two specialized epidermal cells that flank the pore of a stoma and usually cause it to open and close. |
chlorophyll | the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis, and occurring in a bluish-black form, |
chloroplast | a plastid containing chlorophyll |
light dependent reaction | The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis |
light dependent react | something that makes things visible or affords illumination: |
energy pyramid | Energy pyramid An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. |
producer | a person who produces. |
mitochondria | an organelle in the cytoplasm of cells that functions in energy production. |
autotrophs | an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. |
consumers | a person or thing that consumes. |
herbivore | an animal that feeds on plants. |
omnivores | an animal or person that eats food of both plant and animal origin. |
heterotrophs | an organism deriving its nutritional requirements from complex organic substances. |
carnivores | an animal that eats flesh |
decomposers | a person or thing that decomposes. |
spongy layer | a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis -- called also spongy parenchyma, spongy tissue. |
palisade layer | a layer of parallel elongated cells below the epidermis of a leaf. |
raw materials | the basic material from which a product is made. |
oxygen | a colorless, odorless, gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature |
carbon dioxide | a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air |
glucose | a sugar, C6H12O6, having several optically different forms, the common dextrorotatory form (dextroglucose, or -glucose) occurring in many fruits, animal tissues and fluids, etc., and having a sweetness about one half that of ordinary sugar. |
products | a thing produced by labor: |
