Answer:
The Restriction Fragment Length Polymorphism (RFLP) and the Polymerase Chain Reaction (PCR) are techniques used in molecular biology to identify polymorphisms in DNA samples obtained from different species, organisms, varieties, strains, etc. In the case of RFLP, the DNA is digested with restriction enzymes, so the resulting fragments have different lengths, while in the PCR technique the DNA fragments are obtained by successive amplification cycles and they have the same length.
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.
They're plant cells. The green organelles should be chloroplast. They're responsible for photosynthesis.
