Document Summary
Giant meteorite or volcanic activity (iridium and soot found in 65 mil year old layers around globe) _photosynthesis__ provides the earth with _oxygen, organic compounds, and the energy necessary for life here. Living things need to obtain energy from outside sources. Most all organisms _obtain their energy from the sun_ (directly or indirectly) Photosynthesis- _solar energy_ is trapped and stored as _chemical energy_in the bonds of organic molecules. Synthesis of _energy-rich organic molecules (glucose) from energy-poor molecules (co2 and. Uses _co2 as a carbon source_and light-energy as the energy source. _chloroplasts_ are the site of _photosynthesis_ in plants. _chlorophyll_ is the green pigment that gives a leaf its color. _absorption of the light energy that drives photosynthesis (ps)_- Chloroplasts are primarily in cells of _mesophyll_ (in the leaf interior) are the sites of ps- fig. Co2 and h2o enter the leaf through pores called _stomata_(fig.
