Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Scotland on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a ...

The Right Honourable
''The Right Honourable'' (abbreviation: The Rt Hon. or variations) is an honorific Style (form of address), style traditionally applied to certain persons and collective bodies in the United Kingdom, the former British Empire, and the Commonwealth of Nations. The term is predominantly used today as a style associated with the holding of certain senior public offices in the United Kingdom, Canada, New Zealand, and, to a lesser extent, Australia. ''Right'' in this context is an adverb meaning 'very' or 'fully'. Grammatically, ''The Right Honourable'' is an adjectival phrase which gives information about a person. As such, it is not considered correct to apply it in direct address, nor to use it on its own as a title in place of a name; but rather it is used in the Grammatical person, third person along with a name or noun to be modified. ''Right'' may be abbreviated to ''Rt'', and ''Honourable'' to ''Hon.'', or both. ''The'' is sometimes dropped in written abbreviated form, but is ...

Jacobitism
Jacobitism was a political ideology advocating the restoration of the senior line of the House of Stuart to the Monarchy of the United Kingdom, British throne. When James II of England chose exile after the November 1688 Glorious Revolution, the Parliament of England ruled he had "abandoned" the English throne, which was given to his Protestant daughter Mary II of England, and his nephew, her husband William III of England, William III. On the same basis, in April the Convention of Estates (1689), Scottish Convention awarded Mary and William the throne of Scotland. The Revolution created the principle of a contract between monarch and people, which if violated meant the monarch could be removed. A key tenet of Jacobitism was that kings were appointed by God, making the post-1688 regime illegitimate. However, it also functioned as an outlet for popular discontent, and thus was a complex mix of ideas, many opposed by the Stuarts themselves. Conflict between Charles Edward Stuar ...

Scottish Episcopal Church
The Scottish Episcopal Church (; ) is a Christian denomination in Scotland. Scotland's third largest church, the Scottish Episcopal Church has 303 local congregations. It is also an Ecclesiastical province#Anglican Communion, ecclesiastical province of the Anglican Communion. A continuation of the episcopalian "Church of Scotland" as intended by James VI, and as it was from Stuart Restoration, the Restoration of Charles II of England, Charles II to the re-establishment of Presbyterianism in Scotland following the Glorious Revolution, it recognises the archbishop of Canterbury of the Church of England as president of the Anglican Instruments of Communion, but without jurisdiction in Scotland ''per se (Latin), per se''. Additionally, while the British monarch holds the title of Supreme Governor of the Church of England, in Scotland the monarch maintains private links to both the Presbyterian Church of Scotland and the Scottish Episcopal Church. The church is led by a Primus, who is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montrose Library
The Montrose Library is situated in an A-listed Carnegie funded building in the north Angus coastal town of Montrose. It was first opened in 1905 and in 2018 received a £1 million refurbishment to provide it with "flexible, community focused spaces". History In 1901, Scottish philanthropist Dr Andrew Carnegie, responded to a request for funding to provide a public library in Montrose. “I should be very glad indeed to comply with your suggestion and consider it a privilege. If Montrose will adopt the Free Libraries Act and provide a suitable site, I shall be glad to provide money for the building”- Andrew Carnegie. The architect commissioned was J Lindsay Grant of Manchester. The total cost of the building was £7,500 with further contributions from the town of Montrose of £1000, from Mr and Mrs W. Douglas Johnson of £500 and from “Montrosians at home and abroad” of £1000. Contributions for funding the book collection were requested from present and former Mon ...

Matthew Flinders
Captain (Royal Navy), Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British Royal Navy officer, navigator and cartographer who led the first littoral zone, inshore circumnavigate, circumnavigation of mainland Australia, then called New Holland (Australia), New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French at the colony of Isle de France (Mauritius), Isle de France. Although Britain and France were at war, Flinders thought t ...

Palynology
Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments, sedimentary rocks, and even some metasedimentary rocks. Palynomorphs are the microscopic, acid-resistant organic remains and debris produced by a wide variety of plants, animals, and Protista that have existed since the late Proterozoic.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds., 2005, ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimentary rocks and sediments. Palynology does not include diatoms, foraminiferans or other organisms with siliceous or calcareous tests. The name of the science and o ...

Angiosperms
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carbonifero ...

Gymnosperms
The gymnosperms ( ; ) are a group of woody, perennial Seed plant, seed-producing plants, typically lacking the protective outer covering which surrounds the seeds in flowering plants, that include Pinophyta, conifers, cycads, Ginkgo, and gnetophyta, gnetophytes, forming the clade Gymnospermae. The term ''gymnosperm'' comes from the composite word in ( and ), and literally means 'naked seeds'. The name is based on the unenclosed condition of their seeds (called ovules in their unfertilized state). The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants (angiosperms), which are enclosed within an Ovary (botany), ovary. Gymnosperm seeds develop either on the surface of scales or Leaf, leaves, which are often modified to form Conifer cone, cones, or on their own as in Taxus, yew, ''Torreya'', and ''Ginkgo''. The life cycle of a gymnosperm involves alternation of generations, with a dominant diploid sporophyte phase, and a reduced haploid gam ...

Fertilisation
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a zygote and initiate its development into a new individual organism or offspring. While processes such as insemination or pollination, which happen before the fusion of gametes, are also sometimes informally referred to as fertilisation, these are technically separate processes. The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms, the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. History In antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic. In 1784, Spallanzani established the need of in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma (botany), stigma of a plant, later enabling fertilisation and the production of seeds. Pollinating agents can be animals such as insects, for example bees, beetles or butterflies; birds, and bats; water; wind; and even plants themselves. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants. Self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid (biology), hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma (botany), stigma, it germinates and develops a pollen tube which grows down the style (botany), style until it reaches an ovary (botany), ovary. Its two gametes travel down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytoplasmic Streaming
Cytoplasmic streaming, also called protoplasmic streaming and cyclosis, is the flow of the cytoplasm inside the cell, driven by forces from the cytoskeleton. It is likely that its function is, at least in part, to speed up the transport of molecules and organelles around the cell. It is usually observed in large plant and animal cells, greater than approximately 0.1 mm. In smaller cells, the diffusion of molecules is more rapid, but diffusion slows as the size of the cell increases, so larger cells may need cytoplasmic streaming for efficient function. The green alga genus Chara (alga), ''Chara'' possesses some very large cells, up to 10 cm in length, and cytoplasmic streaming has been studied in these large cells. Cytoplasmic streaming is strongly dependent upon intracellular pH and temperature. It has been observed that the effect of temperature on cytoplasmic streaming created linear variance and dependence at different high temperatures in comparison to low temper ...
