Transport in Angiosperms

Transport in Angiosperms. Chapter 36 36.3, 36.4, 36.5. Root systems have a large surface area for anchorage, water, and mineral ion uptake. Shallow roots provide anchorage and collect surface water runoff or nutrients close to the soil surface.

Calvin Cycle and C4 & CAM plants

Calvin Cycle and C4 & CAM plants. Calvin Cycle. 3 processes: 1) Fixation of carbon dioxide (catalyzed by rubisco , makes 3PG) 2) reduction of 3PG to form G3P 3) regeneration of the CO 2 acceptor, RuBP. Calvin cycle. Rubisco is the key enzyme. G3P. One turn of the calvin cycle.

CO 2 -concentrating mechanisms improve photosynthetic efficiency:

CO 2 -concentrating mechanisms improve photosynthetic efficiency: two major CO 2 -concentrating mechanisms in angiosperms: C 4 photosynthetic pathway CAM (Crassulacean Acid Metabolism) pathways operate in addition to the Calvin cycle. C 4 photosynthetic pathway - occurs in C 4 plants
