Opis

Functional Biology of Plants provides students and researchers with a clearly written, well structured whole plant physiology text. Early in the text, it provides essential information on molecular and cellular processes so that the reader can understand how they are integrated into the development and function of the plant at whole-plant level. Thus, this beautifully illustrated book, presents a modern, applied integration of whole plant and molecular approaches to the study of plants. It is divided into four parts: Part 1: Genes and Cells, looks at the origins of plants, cell structure, biochemical processes and genes and development. Part 2: The Functioning Plant, describes the structure and function of roots, stems, leaves, flowers and seed and fruit development. Part 3: Interactions and Adaptations, examines environmental and biotic stresses and how plants adapt and acclimatise to these conditions. Part 4: Future Directions, illustrates the great importance of plant research by looking at some well chosen, topical examples such as GM crops, biomass and bio-fuels, loss of plant biodiversity and the question of how to feed the planet. Throughout the book there are text boxes to illustrate particular aspects of how humans make use of plants, and a comprehensive glossary proves invaluable to those coming to the subject from other areas of life science.

Recenzje

"Martin Hodson and John Bryant have written the most captivating and elementary textbook on modern plant biology. It might be read from cover to cover by anyone seeking an introduction to the subject, but seems especially suited to high school, undergraduate and vocational courses."  (Expl Agric, 1 January 2013)

Named CHOICE Outstanding Title for 2012

Students who are new to plant science will be quite well served, as will graduate students and others needing to develop fuller understandings and perspectives on their research.  Summing Up: Highly recommended.  Lower–division undergraduates through researchers/faculty.   (Choice, 1 November 2012)

Functional Biology of Plants provides students and researchers with a clearly written, well structured whole plant physiology text. Early in the text, it provides essential information on molecular and cellular processes so that the reader can understand how they are integrated into the development and function of the plant at whole–plant level. Thus, this beautifully illustrated book, presents a modern, applied integration of whole–plant and molecular approaches to the study of plants.

The book is divided into four parts:

Part 1: Genes and Cells, looks at the evolutionary origins of plants, cell structure, biochemical processes and genes and development.

Part 2: The Functioning Plant, describes the structure and function of roots, stems, leaves, flowers and seed and fruits development.

Part 3: Interactions and Adaptations, examines environmental and biotic stresses and how plants adapt and acclimatise to these conditions.

Part 4: Future Directions, illustrates the great importance of plant research by looking at some well chosen, topical examples including responses to climate  change, biomass and bio–fuels, loss of plant biodiversity and genetic modification of crop plants.

Text boxes, many of which illustrate particular aspects of how humans make use of plants, are included throughout the text and a comprehensive glossary will prove invaluable to those coming to the subject from other area of life science.

• A modern integration of whole plant and molecular approaches.
• Focuses on the networks of processes and functions within organs and their integration in the whole plant.
• Covers generic aspects of plant development.
• Beautifully illustrated with full colour illustrations throughout.
• Clearly written by two authors with many years of teaching experience.
