Photosynthetic Mechanisms

Introduction

 C3 plants- A plant that utilizes the C3 carbon fixation pathway as the sole mechanism to convert CO2 into an organic compound

C4 plants- A plant that utilizes the C4  carbon fixation pathway in which the CO2 is first bound to a phosphoenolpyruvate in mesophyll cell resulting in the formation of four-carbon compound that is shuttled to the bundle sheath cell where it will be decarboxylated to liberate the CO2 to be utilized in the C3 pathway.

Process

Diagrams of C3 and C4 pant photosynthetic pathway.

Evaluation

C3 PLants are found in areas where there is little amounts of light.

C4 plants are found in areas where there is light.

Conclusion

Similarities:

both C3 and C4 networks are very robust 

Differences:

C4 plants have better modularity 

C3 network exhibit more dense topology structure than C4.
