TERMINOLOGY AND MORPHOLOGY
DIVISIONS OF BOTANY
1. Structural Botany or Plant Morphology treats of the various
organs or parts of a plant, as root, stem, flower, fruit, etc., with their
special forms and modifications. It also includes Vegetable Histology,
that part of structural botany which considers the minute or micro-
scopical structure of plant tissues and Vegetable Cytology, which treats
of plant cells and their contents.
2. Physiological Botany explains how the various parts of the plant
perform their work of growth, reproduction and the preparation of food
for the support of animal life from substances not adapted to that use.
3. Geographical Botany treats of the distribution of plant life on
the globe. The centre of distribution for each plant is the habitat or
original source from which it spreads, often over widely distant regions.
4. Economic or Applied Botany deals with the science from a prac-
tical standpoint, showing the special adaptation of the vegetable kingdom
to the needs of everyday life.
5. Geological Botany treats of the plants of former ages, traceable
in their fossil remains.
6. Systematic Botany or Vegetable Taxonomy considers the classi-
fication or arrangement of plants in groups or ranks according to their
resemblances or differences.
7. Vegetable Ecology treats of plants in relation to their
environment.
