Plant is one of the largest, complex and vital industry with most sequential
processes and functions. These processes and functions take place in variety
of plant structures from the seed stage-seedling stage upto the formation of
plant body ie. from organs, systems and reproductive units. Plant physiology is
actually concerned with functions, structures, processes and response of plants
to different environmental regimes. Thus this course on plant physiology and
metabolism is the study of phenomenon of plant life having structures and
functions with extreme co-ordination forms the subject matter of book Plant
Physiology and Metabolism.
This book is written for S.Y.B.Sc students as per new syllabus 2025 and
NEP 2020 framework. We have tried to present the syllabus matter uptodate and
illustrations have been made as per the need of the course matter, in most lucid
style to understand all students.
This course book covers the topics that introduce scope and importance
of Plant Physiology followed by plant water relations, Water absorption and its
transport in the plant in upward direction. Plants need various inorganic elements
as nutrients for growth and development during which water gets transpired.
Some main growth regulators ideally necessary for full growth and reproductive
development of the plant while nitrogen is key element in nutrition and how it is
fixed, and mechanism of fixation has been elaborated. This terminates in causes
flowering and variety of plant responses for completion upto reproductive stage
are parts of the study.
We authors are thankful to our publisher Shri. Rangrao Patil of Prashant
Publications, Jalgaon for his wholehearted Co-Operation and help for completion
of this book in presentable form. We are extremely thankful to all Staff members
of this publication for their hard work to make this book in a final form,
We hope that this book will find its place among the students as well teachers.
Suggestions and criticisms if any will be thankfully accepted from the readers.
