One
class embraces the functions relating to the life of the individual organism.
These functions have to do with the processes of eating, digesting,
assimilating, taking in of oxygen, producing of energy, and excreting of waste
matters. These may be called the nutritive functions, if the term is used in its
broadest sense. To the second group of activities belong the functions that have
to do with the perpetuation of the animal or plant species, and these are known
as the reproductive functions. Living organisms, whether plant, animal, or
human, may, in the third place, be considered in their relations to one another
and especially to the general welfare of mankind. Thus we may discuss the
beneficial or injurious effects, so far as man is concerned, of different kinds
of insects or of various types of bacteria; we may learn of the activities of
individual men or of groups of individuals which promote or retard the advance
of human society; or we might, if we were to carry the study still farther, even
seek to learn the ways by which the higher thoughts of mankind, as expressed in
poetry, music, and religion, affect the development of the human race.

Plant physiology is the science
which is connected to the material and energy exchange, growth and development,
as well as movement of plant. Plant physiology is the science that studies plant
function: what is going on in plants that accounts for their being alive. The
contents of this notes are as follows : Water and nutrients in plant, Production
of primary and secondary metabolites, Physiology of plant growth and
development, Physiology of plant growth and development, etc.
Climbing plants are plants
which climb up trees and other tall objects. Many of them are vines whose stems
twine round trees and branches. There are quite a number of other methods of
climbing.
This book explains the
following topics: What is Plant Propagation, Propagation in the Past, Modern
Propagation, Sexual Increase of Plants, Vegetative Propagation, Tools and
Equipment, Soils and Growing Media, Propagation in Different Climates, The
Propagation Environment, Plant Problems, Taking Cuttings, Sowing Seeds, Grafting
and Budding, Layering.
This book is intended
primarily for medical students and others who do not necessarily intend to
continue the study of botany, but who desire or are obliged to obtain some
elementary knowledge of plants, particularly in relation to general biology. The
book is based on the first portion, which deals mainly with plants, of the
course in Elementary Biology for the Preliminary Examination in Science.
This lecture note is
targeted to plant scientists who may wish to use tissue culture and produce
transgenic plants at some point in their research careers, but do not
necessarily want to become experts in this area. This note explains the concepts
of plant tissue culture and transformation and provide hands-on experience of
the most common of these techniques in labs and demonstrations of more advanced
or uncommon techniques.
