New research has found that between 1982 and 2020, global plant photosynthesis grew 12 percent, tracking CO2 levels in the atmosphere as they rose 17 percent. Biomass energy is a renewable source of fuel that can be used to heat homes, power vehicles or as an alternative for fossil fuels. Nutrient enrichment (increases in [NO3], [NH4+] and [HPO42-] of 5- to 15-fold over ambient concentrations) resulted in an increase, within hours, in photosynthetic rates measured by both ETR and O2 evolution techniques. This chapter, which also deals with the history of fluorometers, is dedicated to David Walker (19282012), who was a pioneer in the field of photosynthesis and chlorophyll fluorescence. Engineering C 2 photosynthesis, a simple CCM that captures, concentrates, and re-assimilates photorespired CO 2, is a promising approach currently in its infancy. The process of photosynthesis helps in following ways - 1. ; Veins are made primarily of xylem and phloem.They transport water and minerals to the cells of leaves and carry away dissolved sugar. Key points: Photorespiration is a wasteful pathway that occurs when the Calvin cycle enzyme rubisco acts on oxygen rather than carbon dioxide.
