refers to the use of light energy to ultimately provide the energy to convert ADP to , thus replenishing the universal energy currency in living things. In the simplest systems in prokaryotes, photosynthesis is used just for the production of energy, and not for the building of any biological molecules. In these systems there is a process called cyclic photophosphorylation, which just accomplishes the ADP to ATP process for immediate energy for these cells. This process uses only and the chlorophyll P700.

You are now ready to begin your task! Remember--as you scan through the information on the websites listed below, be sure take thorough notes and be sure to really try to get an understanding of what photosynthesis is and what its importance is to life on earth. You are trying to save the world! You will need all the knowledge you have to be able to carry out this important mission.

The product of photosynthesis is a , such as the sugar , and oxygen which is released into the atmosphere (Figure 9l-1). All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight (Figure 9l-1). This chemical reaction is catalyzed by acting together with other , , , , and molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates, such as . Sugars can also be combined with other such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.

Extensive tracts of land in the tropical and subtropicalregions of Asia, Africa and Latin America contain highly weathered andinherently infertile soils. These areas generate low crop yields and are proneto land degradation as a result of deforestation, overgrazing and inadequatefarming practices. In addition to socio-economic factors, the main constraintsare soil acidity and low inherent N and P fertility (Lal, 1990; Formoso, 1999).While N inputs can be obtained from sources such as BNF, crop residues and otherorganic sources, P inputs need to be applied in order to improve the soil Pstatus and ensure normal plant growth and adequate yields. Tropical andsubtropical soils are predominantly acidic and often extremely P deficient withhigh P sorption (fixation) capacities. Therefore, substantial P inputs arerequired for optimum growth and adequate food and fibre production (Sanchez andBuol, 1975; Date ., 1995).

Manufactured WSP fertilizers such as superphosphates arecommonly recommended for correcting P deficiencies. However, most developingcountries import these fertilizers, which are often in limited supply andrepresent a major outlay for resource-poor farmers. In addition, intensificationof agricultural production in these regions necessitates the addition of Pinputs not only to increase crop production but also to improve soil P status inorder to avoid further soil degradation. Therefore, it is imperative to explorealternative P inputs. In this context, under certain soil and climateconditions, the direct application of PRs is an agronomic and economically soundalternative to the more expensive superphosphates in the tropics (Chien andHammond, 1978; Truong ., 1978; Zapata ., 1986; Hammond., 1986b; Chien and Hammond, 1989; Chien ., 1990b; Saleand Mokwunye, 1993).
