1.	Question : Observe the diagram and answer the following. (a) Which group of plants exibit these two type of cells ? (b) What is first product of C_(4) cycle ? (c ) Which enzyme is there in bundle sheath cells and mesophyll cells ?
Answer» Solution :(a) The plants of Graminae or poaceae family like sugarcane and maize two types of CELLS are seen in them, cells of MESOPHYLL tissue and cells of bundle sheath. (b) The first product of `C_(4)` cycle is 4C-oxalo - acetic acid. (c ) PEPcase enzyme is present in bundle sheath cells which does FIXATION of `CO_(2)` of ATMOSPHERE and forms 4C oxalo acetic acid. Which RuBisCO enzyme is found in cells of bundle sheath which fixes `CO_(2)` and forms 3C PGA. PGA = phosphoglyceric acid.
