Document Summary
Giant meteorite or volcanic activity. - iridium and soot found in 65 million year old layers around the 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. Also, it is responsible for the 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.
