Available in PDF, EPUB and Kindle. Book excerpt: he biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. TThis concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are numerous observations which indicate that it is not the cells which serve as the basic units of biological life but that this property falls to some other, subcellular assemblage. To deal with this intricate problem concerning the fundamental unit of living matter, we proposed the so-called Cell Body concept which, in fact, devel ops an exceedingly original idea proposed by Julius Sachs at the end of the 19th century. In the case of eukaryotic cells, DNA-enriched nuclei are intimately associated with a microtubular cytoskeleton. In this configuration—as a Cell Body—these two items comprise the fundamental functional and struc tural unit of eukaryotic living matter. The Cell Body seems to be inherent to all cells in all organisms.

Download or read book The Developmental Biology of Reproduction written by Clement Markert and published by Elsevier. This book was released on 2012-12-02 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Developmental Biology of Reproduction documents the proceedings of the 33rd symposium of the Society for Developmental Biology. Reproductive Biology was selected as the main theme of the symposium. The symposium aimed to draw center attention on basic aspects of reproduction in both plants and animals in the hope of stimulating research that might provide the necessary foundation for effective, practical control of human reproduction. Five areas were selected for emphasis: the formation of eggs and sperm; the activation of the egg to develop into an embryo; the genetic and biochemical events underlying the early development of the embryo; the hormonal controls operating in the reproductive process; and the general control of implantation and growth of the mammalian embryo in the uterus. Thirteen reports were given by distinguished researchers in each of these areas. All biologists interested in a broad understanding of problems of reproduction will find this symposium interesting and important for their own work.

Download or read book Sexual Interactions in Eukaryotic Microbes written by Danton O'Day and published by Elsevier. This book was released on 2012-12-02 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual Interactions in Eukaryotic Microbes provides a comprehensive discussion of the sexual processes of eukaryotic microorganisms. The book is organized into three parts. Part I presents an overview of intercellular communication, covering the modes of cellular communication and the benefit of using eukaryotic microbes for studying cell communication. Part II on pheromonal interactions includes studies on the role of sex pheromones in organisms such as Saccharomyces cerevisiae, Allomyces, Volvox, and Neurospora crassa. Part III on cell surface interactions presents studies such as sexual interactions in Saccharomyces cerevisiae; sexual interactions of the cell surface in Paramecium; and the genetics and cellular biology of sexual development in Ustilago violacea. This book will be of value on a multitude of levels: from a general reference text to a source of research ideas. It will appeal to a wide spectrum of readers in a large number of disciplines, but will be particularly useful to cell biologists, microbiologists, protozoologists, and mycologists interested in the study of cellular communication.

Available in PDF, EPUB and Kindle. Book excerpt: An engaging and richly illustrated exploration of the natural history of seaweeds and other algae As photosynthetic organisms, seaweeds and other algae transfer billions of tons of carbon globally from the atmosphere to the deep ocean each year. Coming in all manner of colors, shapes, and sizes, from bioluminescent single-celled algae to giant kelps, they form the basis of most marine food webs, and are found in almost all environments on the planet. Touted as the biofuel of the future, seaweeds and algae also hold promise for biodegradable packaging, offer a nutritious food source, and exhibit antiviral and antitumor properties. Combining accessible text with stunning images and graphics, this book takes a deep dive to explore the unique characteristics of seaweeds and other algae, outlining their extraordinary evolution as well as their morphology, life histories, ecology, and uses. Offering rare insights into the algal world, The Lives of Seaweeds is essential reading for naturalists and marine life enthusiasts.

Download or read book Principles of Animal Biology written by Aaron Franklin Shull and published by . This book was released on 1920 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zoölogy is the science of animals. This was the definition centuries ago, when zoölogy was almost exclusively the classification and naming of animals. Since that time there has arisen a vast body of doctrine concerning modes of life, life processes, inter-relations of animals, development, distribution, and descent, most of which has little bearing on classification, which is now founded upon principles as basic as those underlying other branches of science. For the purposes of this volume, anything that has to do with animals is part of zoölogy. This book is, in practice, one long definition of zoölogy. It includes morphology, physiology, ecology, zoögeography, paleontology, taxonomy, and evolution as part of the zoölogical sciences. This book, being a general discussion, will contain elementary facts and principles from each of these branches of science. Students should find it a useful exercise to stop and reflect which of the divisions of zoölogy are, at any given moment, actually being studied.
