Document Summary
1 (co2 and h2o: autotrophic nutrition, heterotrophic nutrition. Synthesis of energy-rich organic molecules from energy-poor molecules. Uses co2 as a carbon source and light-energy as the energy source. Directly or indirectly supplies energy to most living organisms. Photosynthesis transforms light energy trapped by chloroplasts into chemical bond energy and stores that energy in sugar and other organic molecules. >>>>>plants and other autotrophs are the producer of the biosphere. Organisms acquire organic molecules used for energy and carbon skeletons (a. k. a. food) by one of two nutritional modes: >>>>>chloroplasts are the site of photosynthesis in plants. Leaves are the major organs of photosynthesis (see fig 10. 4) Water is absorbed by the roots and transported to the leaves through the. Chloroplasts are primarily in cells of mesophyll (in the leaf interior) Chlorophyll is the green pigment that gives a leaf its color chlorophyll is also responsible for the absorption of the light energy that drives photosynthesis.
