About the Book
Botany is the scientific study of plants. It examines their structure, growth, reproduction, development, diseases, ecology and evolution and the integral roles that plants play in the functioning of both terrestrial and marine ecosystems.
This text book entitled ‘Structural Botany (Anatomy, Embryology and Palynology)’ is divided in 3 parts the first part is devoted towards Anatomy, the second part pertains to Embryology and the third part explains Palynology. Plant Anatomy or phytotomy is the general term used for the study of the internal structure of plants. Embryology is the study of the embryo development. Palynology is the study of plant pollen, spores and certain microscopic plankton organisms in both living and fossil form.
Botanists study how plants evolve and adapt to changing climate and environments as well as the ecological interactions between plants and other organisms, and plays an active role in understanding and conserving biodiversity. Botany comprises various sub-disciplines each studying a different aspect of plants.
This book is for the students of S.Y. B.Sc. General Science and is strictly as per the syllabus of University of Pune. However the book will benefit students who are pursuing Botany or any other life sciences. Diagrams and charts are included for the benefit of the students and to explain topics in detail.
Studying Botany will help students who desire to pursue a career as a Botanist or in any other life sciences.
