NCERT Book Class 11 Biology Chapter 5 Morphology of Flowering Plants

UNIT 2
STRUCTURAL ORGANISATION
IN PLANTS AND ANIMALS

Chapter 5 The description of the diverse forms of life on earth was made only by
Morphology of observation – through naked eyes or later through magnifying lenses
Flowering Plants and microscopes. This description is mainly of gross structural features,
both external and internal. In addition, observable and perceivable
Chapter 6 living phenomena were also recorded as part of this description. Before
Anatomy of Flowering experimental biology or more specifically, physiology, was established
Plants as a part of biology, naturalists described only biology. Hence, biology
remained as a natural history for a long time. The description, by itself,
Chapter 7 was amazing in terms of detail. While the initial reaction of a student
Structural Organisation in could be boredom, one should keep in mind that the detailed description,
Animals was utilised in the later day reductionist biology where living processes
drew more attention from scientists than the description of life forms
and their structure. Hence, this description became meaningful and
helpful in framing research questions in physiology or evolutionary
biology. In the following chapters of this unit, the structural organisation
of plants and animals, including the structural basis of physiologial or
behavioural phenomena, is described. For convenience, this description
of morphological and anatomical features is presented separately for
plants and animals.
