The section of the leaf shows a structure which affords effective protection against the hot, dry weather of most cycad localities (Fig. 29). The highly cutinized surface is almost impervious to water, and the stomata, or pores, on the under side of the leaf have a form well adapted to keeping the opening closed except when the air is full of moisture. Long, narrow cells with thick, Fig. 30.--Dioon spinulosum at Tierra Blanca, Mexico; plants growing on rocks with little soil, showing exposed roots; at the right the base of a trunk with an exposed root (+) nearly as large as the trunk itself. corky walls are abundant, and they give the leaf a maximum of rigidity combined with elasticity. THE ROOT No extensive study of the cycad root has been undertaken. There is a main tap root which tapers gradually and extends down to a great depth, so that small amounts of water are brought up even when the surface soil is very dry. Lateral branches are usually small and weak. When plants are growing on exposed rocks where there is little soil, the root development is remarkable (Fig. 30). In the specimen shown in the figure the upper part of the roots is entirely exposed. Sometimes such roots may extend along the exposed rock for many feet before entering the soil. In an extreme case a root was exposed for forty feet before it finally entered the soil. A peculiar feature of the root has attracted much more attention and investigation than the normal structure itself. The small, lateral roots often become infected by "bacterioids" which cause a swelling accompanied by a profuse dichotomous branching, and besides the roots begin to grow up instead of down, soon emerging above the surface of the soil in dense coralloid...

Available in PDF, EPUB and Kindle. Book excerpt: Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.

Download or read book New Organic Architecture written by David Pearson and published by . This book was released on 2001 with total page 1308 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Organic Architecture is a manifesto for building in a way that is both aesthetically pleasing and kinder to the environment. It illuminates key themes of organic architects, their sources of inspiration, the roots and concepts behind the style, and the environmental challenges to be met. The organic approach to architecture has an illustrious history, from Celtic design, Art Nouveau, Arts and Crafts, to the work of Antoni Gaud� and Frank Lloyd Wright. Today there is a response to a new age of information and ecology; architects are seeking to change the relationship between buildings and the natural environment. In the first part of his book, David Pearson provides a history and assessment of organic architecture. The second part comprises statements from thirty architects from around the world whose work is based on natural or curvilinear forms rather than the straight-line geometrics of modernism. Each statement is accompanied by full-color illustrations of one or several of the architects' built projects.

Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedia offers access to the diversity of ferns and seed plants, the most important groups of green land plants. Available information of general and systematic relevance is synthesized at the level of families. Evidence from virtually all disciplines important to modern taxonomy makes the work a most valuable source of reference not only for taxonomists, but for all who are interested in the various aspects of plant diversity. A revised classification includes a complete inventory of genera along with their diagnostic features, keys for identification, and references to the literature. The first volume deals with pteridophytes and gymnosperms.

Download or read book Anatomical Adaptations of Halophytes written by Marius-Nicușor Grigore and published by Springer. This book was released on 2017-10-04 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes important anatomical adaptations in halophytes, based on a large review of relevant literature (since the 17th century) and recent research findings. Scientists involved in the study of plant biology, from a molecular to ecosystemic level, will find information about all major structural strategies of salt tolerant plants. The book starts with an introductory theoretical background, where several aspects related to the definition and classification of halophytes and saline environments are included. Major anatomical adaptations are then grouped around major concepts: succulence, tracheoidioblasts, salt secretion, Kranz anatomy, successive cambia, and bulliform cells. Each of them is treated following a general scheme: introductory considerations, anatomical basis, and ecological implications; a review of relevant literature is then conducted and the text is supported by a large number of figures, especially ink drawings and color micrographs.

Download or read book The Plant Stem written by Fritz H. Schweingruber and published by Springer. This book was released on 2018-06-13 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique and attractive open access textbook combines the beauty of macroscopic pictures of plant stems with the corresponding colorfully stained images of anatomical micro-structures. In contrast to most botanical textbooks, it presents all the stem characteristics as photographs and shows the microscopic reality. The amount of text is reduced to a minimum, and the scientific information is highlighted with short legends and labeled photographs, allowing readers to focus on the pictures to easily understand how the anatomical structures relate to genetic, ecological, decomposition and technical influences. It includes a chapter devoted to simple anatomical preparation techniques, and further chapters showing the cell content, cell walls, meristematic tissues and stem structures of all major taxonomic units and morphological growth forms in various ecological and climatic regions from subarctic to equatorial latitudes, as well as structures of fossil, subfossil and technically altered wood. This textbook appeals to students and researchers in the fields of plant anatomy, taxonomy, ecology, dendrochronology, history, plant pathology, and evolutionary biology as well as to technologists.

Download or read book Plants in Mesozoic Time written by Carole T. Gee and published by Indiana University Press. This book was released on 2010-07-16 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants in Mesozoic Time showcases the latest research of broad botanical and paleontological interest from the world's experts on Mesozoic plant life. Each chapter covers a special aspect of a particular plant group -- ranging from horsetails to ginkgophytes, from cycads to conifers -- and relates it to key innovations in structure, phylogenetic relationships, the Mesozoic flora, or to animals such as plant-eating dinosaurs. The book's geographic scope ranges from Antarctica and Argentina to the western interior of North America, with studies on the reconstruction of the Late Jurassic vegetation of the Morrison Formation and on fossil angiosperm lianas from Late Cretaceous deposits in Utah and New Mexico. The volume also includes cutting-edge studies on the evolutionary developmental biology ("evo-devo") of Mesozoic forests, the phylogenetic analysis of the still enigmatic bennettitaleans, and the genetic developmental controls of the oldest flowers in the fossil record.
