Used to treat dimentia in mountains

the studies of plants used by primitive and aboriginal people

dynamic complex of a plant, animal, microorganism communities and the non-living environment interacting as a functional unit

variability among living things

obtained from ecosystems including food and fiber ex. –> plants as medicine

benefits obtained from the regulation of ecosystem processes including air control, water regulation, erosion control, water purification, regulation of human disease, biological control, pollination and storm protection.

nonmaterial services obtained from spiritual enrichment, cognitive development, reflection, recreation and aesthetic experiences

those necessary for the production of all other ecosystems. these occur over a long time or are indirect

ctually used the substances, was in Oklahoma, Mexico, and mainly northwest amazon

organisms able to harvest the carbon they need directly from inorganic compounds such as O2.

they use light energy from the sun to break CO2 molecules and make glucose

the process by which photosynthetic organisms use light energy to drive the synthesis or organic (carbon) compounds from CO2. ** 6 CO2 + 12H2O + light energy –> C6H12O6 + 6H2O ** all the reduced carbon is returned to the atmosphere as O2 and the the carbon dioxide is used to form carbs when mixed with water (carbon reduction) (glucose - 6 Carbon sugar)

light dependent happens in the chloroplasts, and results in NADPH. Light independent involves the NADPH and ATP from the light dependent reaction to form sugar from CO2 with a 5 carbon molecule

gases that trap heat in atmosphere (CO2, Methane ((H4)), Nitrous Oxide ((N2O)), fluorinated gases) methane from transport of coal, natural gases, oil, livestock, agricultural practices, landfills nitrous oxide from fossil fuels

process of atmospheric CO2 is taken up by trees, grasses, and other plants through photosynthesis and stored as carbon In biomass (trunks, branches, foliage) and soils

allow for a plant to absorb the water and nutrients from the soil for use in chemical synthesis

• dominant central taproot- root from which secondary roots radiate • secondary roots- can produce more roots

form when initial root dies and new roots emerge from tissue at the base of the plant since they come from the stem rather than root tissue, they are adventitious roots

stem- provides framework and displays flowers conductive system- carries nutrients and H2O up leaves- maximizes surface area for photosynthesis and can store water

nepenthes lead- pitcher for capturing bugs thistle leaves- stiff tips to deter deer citrus leaves- contains puke inducing oils crassulacae- strores H2O poinsettas- attract pollinators

spherical underground storage stems

swollen underground stems that grow horiz

provides energy for sprouting the next season - they r stems that creep underground

pollen grain could travel far in dry climates
