1.	Question : In what kind of plants do you come across 'Kranz' anatomy? To which conditions are those plants better adapted? How are these plants better adapted than the plants which lack this anatomy.
Answer» Solution :Kranz anatomy refers to the dimorphism in the chloroplast structure. It is found in `C_(4)` plants. The cell of leaves have two type of chloroplast in them. Granal Chloroplast It is found in the mesophyll cells of leaves. Chloroplast have well developed grana in them. These chloroplast effectively fix `CO_(2)` even if it is present in lower concentrations. PEP caboxylae is present with fix `CO_(2)` and to form oxaloacetic acid (4 carbond dioxided ). Agranal Chloroplast Present in bundle sheath cells of the leaves. `C_(3)` cycle occurs in these cell with the presence of RuBisCo enzyme. The `C_(4)` plants are well ADAPTED to high `O_(2)` concentration and high temperature. `C_(4)` plants can absorb `CO_(2)` even when `CO_(2)` concentration in much LOW thus `C_(4)` plants can perform high rate of photosynthesis even the stomata are closed or there is the shortage OFWATER thus, they can conserve water. Since, PEP- carboxylase isinsenitive to `O_(2)` thus excess `O_(2)` has us inhibitory EFFECT in `C_(4)` PATHWAY and there is no photosynthesis in `C_(4)` plants. Thus, `C_(4)` plants are better adapted to tropical and desert ( hot acid habitats ) areas than the plants, that lack this anatomy.
