Core angiosperms. They are distinguished from gymnosperms by characteristics including flowers , endosperm within their seeds , and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant.

Botany , also called plant science s , plant biology or phytology , is the science of plant life and a branch of biology. A botanist , plant scientist or phytologist is a scientist who specialises in this field. Nowadays, botanists in the strict sense study approximately , species of land plants of which some , species are vascular plants including approximately , species of flowering plants ,  and approximately 20, are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify — and later cultivate — edible, medicinal and poisonous plants, making it one of the oldest branches of science. Medieval physic gardens , often attached to monasteries , contained plants of medical importance. They were forerunners of the first botanical gardens attached to universities , founded from the s onwards.
It includes the study of fossils to classify organisms and study interactions with each other and their environments their paleoecology. Paleontology lies on the border between biology and geology , but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry , mathematics , and engineering. Use of all these techniques has enabled paleontologists to discover much of the evolutionary history of life , almost all the way back to when Earth became capable of supporting life, about 3. As knowledge has increased, paleontology has developed specialised sub-divisions, some of which focus on different types of fossil organisms while others study ecology and environmental history, such as ancient climates.
Palynology , scientific discipline concerned with the study of plant pollen , spores , and certain microscopic planktonic organisms , in both living and fossil form. The field is associated with the plant sciences as well as with the geologic sciences, notably those aspects dealing with stratigraphy , historical geology , and paleontology. Palynology also has applications in archaeology , forensic science and crime scene investigation, and allergy studies. Accordingly, the scope of palynologic research is extremely broad, ranging from the analysis of pollen morphology with electron microscopes to the study of organic microfossils palynomorphs extracted from ancient coals. As pollen and spores are produced in large numbers and dispersed over large areas by wind and water, their fossils are recoverable in statistically significant assemblages in a wide variety of sedimentary rocks.

Walat Formation is equivalent to Bayah Formation. This formation is the beginning of Bogor basin deposition. In this case, age and environment of this formation have been analyzed by previous researchers, but the results of age and environment interpretations have different ranges, especially from its palynological aspect which until now Walat Formation is rarely analyzed using this aspect. This research was conducted to identify the age and depositional environment of Walat Formation in Sukabumi region by using pollen and spores to confirm different interpretations of previous studies. Measure section was carried out in sampling and chemical treatment method was carried out to see palynomorph content in the rock.

University Ave. Recent advances in microscopy, imaging, and data analyses have permitted both the greater application of quantitative methods and the collection of large data sets that can be used to investigate plant morphology. This special issue, the first for Applications in Plant Sciences , presents a collection of papers highlighting recent methods in the quantitative study of plant form. These emerging biometric and bioinformatic approaches to plant sciences are critical for better understanding how morphology relates to ecology, physiology, genotype, and evolutionary and phylogenetic history.

Господи Исусе. Раздался телефонный звонок. Директор резко обернулся. - Должно быть, это Стратмор.
Беккер не сразу почувствовал, что его кто-то подталкивает. Подняв глаза, он увидел старика с усыпанным родинками лицом, который стоял перед ним, намереваясь пройти. Беккера охватила паника.
Стратмор наклонился и, зачерпнув воды, смыл со своих рук частицы плоти Чатрукьяна. Его мечта о Цифровой крепости рухнула, и он полностью отдавал себе в этом отчет. Теперь у него осталась только Сьюзан.
Сьюзан подняла. На плюшевом диване, закутавшись в махровый халат, грелся на солнце Дэвид и внимательно за ней наблюдал. Она протянула руку, поманив его к. - Без воска? - тихо спросила она, обнимая. - Без воска.

Я из отдела испанской полиции по надзору за иностранными туристами. В вашем номере проститутка. Немец нервно посмотрел на дверь в ванную. Он явно колебался.
В тот момент Сьюзан поняла, за что уважает Тревора Стратмора. Все эти десять лет, в штиль и в бурю, он вел ее за. Уверенно и неуклонно. Не сбиваясь с курса.
Сознание гнало ее вперед, но ноги не слушались. Коммандер. Мгновение спустя она, спотыкаясь, карабкалась вверх по ступенькам, совершенно забыв о таящейся внизу опасности. Она двигалась вслепую, скользя на гладких ступеньках, и скопившаяся влага капала на нее дождем. Ей казалось, что пар буквально выталкивает ее наверх, через аварийный люк.
