In C4 plants, photosynthesis is compartmentalized into two; light-dependent stage and light independent stage. The light-dependent stage occurs in the mesophyll cells of the leaf. Here, CO2 is fixed into oxaloacetate by PEP carboxylase enzyme. The oxaloacetate is then converted to malate that is then transported to bundle-sheath cells (around the leaf veins). The CO2 is then released from the malate and the gas molecule is subsequently fixed by RuBiSCO like in C3 plants. The biggest advantage of C4 photosytheis is that the wasteful process of photorespiration is greatly reduced.
Answer:
Plantae, Archaebacteria, Eubacteria, and potentially fungi. I say potentially because I am not 100% certain if all organisms falling under the category of fungi contain cell walls.
It’s because they’re curious or they get peer pressured into doing it to “fit in.”
