Zdeněk Černohorský
Zdeněk Černohorský (27 December 1910 – 5 September 2001) was a Czech lichenologist and educator. Life and career Zdeněk Černohorský was born in a poor family of a village baker in the village Chroustovice (east Bohemia). Černohorský attended Charles University in Prague. He graduated in 1933 with a degree in natural sciences with a specialisation in lichenology. Following university he taught in several schools–first, a primary school in Chroustovice, and later, secondary schools in Český Krumlov, Mělník and Prague. In 1938 he lost a lot of his property following involuntary resettlement resulting from the Munich Agreement. After WWII, Černohorský was able to start his professional career at the University of Agriculture and Forestry (now the Czech University of Life Sciences Prague). In 1949 he received his habilitation, and that same year was appointed professor at the Faculty of Education at Charles University. In 1959, he was transferred to the Faculty ...

Dean (education)
Dean is a title employed in academic administrations such as colleges or universities for a person with significant authority over a specific academic unit, over a specific area of concern, or both. In the United States and Canada, deans are usually university professors who serve as the heads of a university's constituent colleges and schools. Deans are common in private preparatory schools, and occasionally found in middle schools and high schools as well. Origin A "dean" (Latin: '' decanus'') was originally the head of a group of ten soldiers or monks. Eventually an ecclesiastical dean became the head of a group of canons or other religious groups. When the universities grew out of the cathedral schools and monastic schools, the title of dean was used for officials with various administrative duties. Use Bulgaria and Romania In Bulgarian and Romanian universities, a dean is the head of a faculty, which may include several academic departments. Every faculty unit of u ...

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Textbook
A textbook is a book containing a comprehensive compilation of content in a branch of study with the intention of explaining it. Textbooks are produced to meet the needs of educators, usually at educational institutions, but also of learners (who could be independent learners outside of formal education). Schoolbooks are textbooks and other books used in schools. Today, many textbooks are published in both print and digital formats. History The history of textbooks dates back to ancient civilizations. For example, Ancient Greeks wrote educational texts. The modern textbook has its roots in the mass production made possible by the printing press. Johannes Gutenberg himself may have printed editions of ''Ars Minor'', a schoolbook on Latin grammar by Aelius Donatus. Early textbooks were used by tutors and teachers (e.g. alphabet books), as well as by individuals who taught themselves. The Greek philosopher Socrates lamented the loss of knowledge because the media of transmis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruciferae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are '' Draba'' (440 species), '' Erysimum'' (261 species), '' Lepidium'' (234 species), '' Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetables, including species suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monograph
A monograph is generally a long-form work on one (usually scholarly) subject, or one aspect of a subject, typically created by a single author or artist (or, sometimes, by two or more authors). Traditionally it is in written form and published as a book, but it may be an artwork, audiovisual work, or exhibition made up of visual artworks. In library cataloguing, the word has a specific and broader meaning, while in the United States, the Food and Drug Administration uses the term to mean a set of published standards. Written works Academic works The English term ''monograph'' is derived from modern Latin , which has its root in Greek. In the English word, ''mono-'' means and ''-graph'' means . Unlike a textbook, which surveys the state of knowledge in a field, the main purpose of a monograph is to present primary research and original scholarship. This research is presented at length, distinguishing a monograph from an article. For these reasons, publication of a monograph ...

Seed Plant
A seed plant or spermatophyte (; New Latin ''spermat-'' and Greek ' (phytón), plant), also known as a phanerogam (taxon Phanerogamae) or a phaenogam (taxon Phaenogamae), is any plant that produces seeds. It is a category of embryophyte (i.e. land plant) that includes most of the familiar land plants, including the flowering plants and the gymnosperms, but not ferns, mosses, or algae. The term ''phanerogam'' or ''phanerogamae'' is derived from the Greek (), meaning "visible", in contrast to the term "cryptogam" or " cryptogamae" (, and (), 'to marry'). These terms distinguish those plants with hidden sexual organs (cryptogamae) from those with visible ones (phanerogamae). Description The extant spermatophytes form five divisions, the first four of which are classified as gymnosperms, plants that have unenclosed, "naked seeds": * Cycadophyta, the cycads, a subtropical and tropical group of plants, * Ginkgophyta, which includes a single living species of tree in the genus '' ...

Plant Morphology
Phytomorphology is the study of the physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarity of plan and origin".

Plant Anatomy
Plant anatomy or phytotomy is the general term for the study of the internal Anatomy, structure of plants. Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure. Plant anatomy is now frequently investigated at the Plant cell, cellular level, and often involves the sectioning of tissue (biology), tissues and microscopy. Structural divisions Some studies of plant anatomy use a systems approach, organized on the basis of the plant's activities, such as nutrient transport, flowering, pollination, embryogenesis or seed development. Others are more classically divided into the following structural categories: * Flower anatomy, including study of the Sepal, calyx, Corolla (flower), corolla, androecium, and gynoecium * Leaf#Anatomy (medium and small scale), Leaf anatomy, including study of the Epidermis ...

Rhizocarpon
''Rhizocarpon'' is a genus of crustose, saxicolous (or sometimes lichenicolous), lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen (''Rhizocarpon geographicum''). Taxonomy and phylogeny Together with three small genera ('' Catolechia'', '' Poeltinula'' and '' Epilichen''), ''Rhizocarpon'' constitutes the family Rhizocarpaceae. Historically, ca 389 names have been used. However, many species concepts are ill-defined, many names have been synonymized and new species are regularly being described, so true number of species is not entirely clear as of now, but is estimated to be around 200. In molecular work, the genus has also been shown to be paraphyletic, with closely related genera being nested within ''Rhizoc ...
