NCERT Book Class 11 Biology Chapter 11 Photosynthesis in Higher Plants

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
Plant Growth and Description of physiological processes, in flowering plants as an
Development example, is what is given in the chapters in this unit. The processes of
photosynthesis, respiration and ultimately plant growth and
development are described in molecular terms but in the context of
cellular activities and even at organism level. Wherever appropriate,
the relation of the physiological processes to environment is also
discussed.
