Chapter Summary

--- PAGE 1 --- UNIT 4 PLANT PHYSIOLOGY Chapter 11 The description of structure and variation of living organisms over a Photosynthesis in Higher period of time, ended up as two, apparently irreconcilable perspectives Plants on biology. The two perspectives essentially rested on two levels of organisation of life forms and phenomena. One described at organismic Chapter 12 and above level of organisation while the second described at cellular Respiration in Plants and molecular level of organisation. The first resulted in ecology and related disciplines. The second resulted in physiology and biochemistry. Chapter 13 Description of physiological processes, in flowering plants as …
