Description

Angiosperms, or flowering plants, are one of the most diverse plant groups on the planet, and they offer tremendous resources for a broad range of industries. Flowering Plants examines the anatomy and morphology of angiosperms with a focus on relating their metabolic activities to products for the pharmaceutical, food, cosmetic, and textile industries.

This up-to-date reference provides a thorough understanding of plant structure and chemical and molecular processes found in angiosperms. It covers many important topics on applied botany, and therefore, can also be used as a textbook for students of related fields.  It details the latest research in the field, along with areas in need of further study, for students, researchers, and professionals working in industry. The book takes advantage of technological innovations to showcase a range of advanced techniques for studying plant structure and metabolites, such as cryo-electron microscopy, ultramicroscopy, x-ray crystallography, spectroscopy, and chromatography. Filled with helpful illustrations, diagrams, and flowcharts to aid comprehension, Flowering Plants offers readers the morphological, anatomic, and molecular knowledge about angiosperms they need for a range of industrial applications.
