Introduction
c3 plants use carbon fixation in air only in the mesophyll using RUBP to convert carbon dioxide and ribulose biphosphate into the first stable ion, 3 phosphoglycerate which will consit of 2 PCR cycles in the mesophyll. The reproduction of this is lower concidering it is a much slower cycle. Photorespiration is used in this process to supply more h2o available for the c3 plants. Using most of the water that they recieve through transpiration, but they will not be able to survive with lots of heat because the ribisco needs a lot of oxygen. In c4 plants they dont use air to fixate, yet they do consist of a 4 carbon coumpound called phosphoenol pyruvate that receives the carbon to produce a stable oxaloacetic acid in the mesophyll.
Task
in both c3 and c4 plants the stomata is opened during the day accepting the same amount of carbon dioxide. Both of them produce glucose in cycles such as photosynthesis, calvin benson cycle, c3 acids and light-dependent and independent reactions. but the difference between the both of them are that c3 plants use more cycles of carboxylation, and Pi and starch is the different substance in the c3 plants and in the c4 plants have phosphoenol pyvurate. Regeneration in c4 plants are different processes in the c3 plants allowing it to open and close their stomata thoughout the night.
Process
Such plants as wheat, bluegrass, barley, potatoes sugar beet rice, etc, are a phtosynthetic pathway for c3 plants. each plants have environmental conditions, for exemple bluegrass takes to shade and has a tolerence to low tempurtures.
The secound photo shows the photosynthetic pathway of c4 plants which consists of corn, sugar cane, goose grass, etc, these conditions of species will consist of different needs. for exemple corn will need light and moisture, with warmer tempurtures, while pigweed needs hot dry places with high altitudeand sol
ar radiation.
