Document Summary

Autotrophs: make their own food plants: ultimate source of organic molecules for all other organisms. Photoautotrophs: use the energy of light plants, unicellular and multicellular algae, and photosynthetic prokaryotes: clothe us (cotton), house us (wood), and provide energy for warmth, light, transport, and manufacturing. Heterotrophs: cannot make their own food but must consume plants or animals or decompose organic material. 7. 2 photosynthesis occurs in chloroplasts in plant cells. Chloroplasts are concentrated in the cells of the mesophyll, the green tissue in the interior of the leaf: about 30 to 40 in one mesophyll. House much of the machinery that converts light energy to chemical, which is used in the stroma to make sugar. 7. 3 scientists traced the process of photosynthesis using isotopes. 6co2 + 6h20 c6h12o6 + 6o2. O-18 (isotope of oxygen) used to follow the fate of oxygen atoms during photosynthesis: revealed oxygen comes from water and not carbon dioxide.
