About the Book
"Plants are the living, multicellular, eukaryotic organisms, which belongs to the kingdom Plantae. There are more than 3000,000 species of plants. The science of the structure of the organized plant body learned by dissection is called Plant Anatomy. In general, Plant Anatomy refers to study of internal morphology, pertaining to different tissues. The subject of this chapter is structure of Angiosperms, with emphasis on primary tissues. Plants play a key role in the history of life on planet earth. Plants provide us with oxygen, food, fuel and fiber. Among other reasons, scientists study plants to improve and secure the food supply for an increasing world population, identify new sources of bioactive compounds and medicines, improve fiber production and identify sources of biofuels and biorenewable resources. Plants are the main responsible for the addition of oxygen gas to the atmosphere. They are the only source of food for both animals and humans. They are the primary habitat for millions of other organisms. The world’s population is growing. The climate is changing. Habitats are disappearing and we don’t even have names for many of the species that are disappearing forever. Plants significantly impact our everyday lives and will become increasingly important to meet emerging societal needs. Our knowledge in plant science allows us to enhance world food supplies, improve the nutritional value of crops, reduce environmental pollution, manage invasive species, preserve biodiversity, enhance the urban landscape, and develop new products. Society’s current reliance on plants and future challenges require scientists educated in a variety of disciplines. Understanding plant anatomy is not only fundamental to the study of plant systematics and palaeobotany, but is also an essential part of evolutionary biology, physiology, ecology, and the rapidly expanding science of developmental genetics.
Two-Volume ‘Brig’s Handbook of Methods & Research in Plant Anatomy’ covers all aspects of plant structure and development. It aims to provide for the student a means of articulating the theoretical and practical understanding of material with the best of modern theory and interpretation. The growth and development of tissues and organs are controlled in part by groups of cells called meristems. This work gives a description of meristems, the structure and function of the tissues and organs, modifications of the organs, and illustrates the structure of fruits and seeds and how these are modified for dispersal. In the 21st century, plant anatomy remains highly relevant to systematics, paleobotany, and the relatively new science of developmental genetics, which interfaces disciplines and utilizes a combination of techniques to examine gene expression in growing tissues. Modern students need to consider information from an increasingly wide range of sources, most notably integrating morphological and molecular data."
