Plant Biology questions ---angiosperm questions - Assignment Example Cotyledons are tiny structures found in seed and they form leaves during their later developments. Nonetheless, among the angiosperm species include dandelions with genus Taraxacum in the family Asteraceae. Additionally, there is the Orchis adenocheilae  species of the Orchis genus in the family of Orchis or the orchidaceae. Dandelions (Taraxacum officinale) are a weed that is common in North America. They are nuisance in lawns; however, they also appear in garden beds. They are dark green with jagged edged leaves that are arranged in circular rosettes (Martin, 2005; PG. 05). Their stems usually rise from rosettes with bright yellow tops. They can be described as daisy shaped flowers that often open in mid spring after which they quickly puff white seed heads. Each seed has parachute that flies off with wind; thus, they are dispersed by wing (Dodson, n.d.; PG. 01). These seeds germinate eagerly; however, they take time to have footholds. They often bloom in nearly all seasons and r eadily survive winter that affects nearly the entire North America (Wachman, n.d.; 01). They have deep taproots which readily sprout new leaves if root is not killed or removed. When damaged, the entire plant seep milky sap. Alternatively, the Orchis adenocheilae  has different characteristics that make them distinguished from other flowers. The sexual portions of Orchis adenocheilae  are different from other flowers in that they are characterized by reduced number of sexual portions (Jacquemyn et al. 2011; pg. 01). The general flower is characterized by style, filaments, anthers, and stigma, features that are reduced in Orchis adenocheilae  and fused into a single structured referred to column. Orchids have only one anther that is situated at the apex of their column (Yang, 2011; PG. 01). Additionally, an orchid’s ovary has three carpels that fused to an outward evidence of existing three ridges that are found on the outside of seed pods. Notably, a mature orchid seed opens usually opens about the middle juncture between the lines. Therefore, the seeds of this flower are dispersed through self dispersion. The ovules are often arranged in the inside of the ridges of the ovary where they do not develop until the flower is pollinated; therefore, the delay between pollination and opening up of the dry pod. Finally, it is worth noting that petals and sepals are quite distinct in orchids and have remained the main distinction between them and other flowers (Garden and Landscape Tips, n.d.; pg. 01). Their petals are referred to labellum or lip. Two or up to three of these sepals are usually joined to a column and their fertile stamens are usually located on one side on the flower. Finally, it is worth noting that orchids depend on self and cross- pollination. Nonetheless, it is worth noting that orchids in hot regions depend on cross pollination that is facilitated by different types of bees while those in cold regions depend on self pollination (Dodson , n.d.; PG. 01). However, they depend on mycorrhizal fungi to complete their life cycle especially at their early stage of development. The Orchids is the largest angiosperm and has nearly two thousand species including the Orchis adenocheilae. In the communities in the ecological system, species usually interact with one another to form a complex and a highly structured network. These network structures usually vary

Research Paper Example In 2007, Singapore was able to generate $9.4 billion USD in tourism revenue which makes up three percent of the country’s entire gross domestic product (Research and Markets 1). This growth in tourism is sparked by the development of the National Tourist Offices operated by the government, with a variety of strategic alliances with such companies as the airline Cathay Pacific and Singapore Airlines (Riege and Perry 1294). It was only recently that the government recognized that casino gaming could represent a significant marketing opportunity to boost more international interest in tourism. There has been significant social disparity occurring in Indonesia about the viability and economic benefits of casino gambling which has, until just recently, prevented development of casinos as part of a new tourism philosophy. In 2011, petitioners asked the Singaporean Constitutional Court to declare certain provisions and regulations to be held unconstitutional that had, previously, pro hibited gambling in any form in the country. At the same time, government has been attempting to elicit foreign investment from major hospitality companies to develop and launch casino gambling as a means of improving its competitive marketing position internationally. This conflict stems from concern over the many low-wage citizens in the country, believing that casino gambling would detract from their quality of living. However, despite these concerns, the government and the court systems have relaxed the many strict regulations prohibiting gaming in this fashion, thereby allowing development of the first casino gambling facility in 2012 in the city of Bintan. The only major player in the gaming operations in Singapore is Malaysia-based Landmarks Bhd., an investment holding company operating a diverse portfolio of hospitality businesses internationally. The Las Vegas Sands, one of Landmarks’ largest shareholders, has been integral in petitioning the Singaporean government t o allow development and relax regulatory pressures denying such construction. Upon development of the Landmarks’ gaming project, it is expected that total revenues stemming from gaming will increase 16 percent to $30.3 billion (Hin 2). The social impact of gaming in Singapore is substantial. There is evidence that low-income citizens in the country maintain social characteristics that will ultimately lead to gambling addictions. Some have even turned to criminal behaviors as a means of sustaining this addiction, which has concerned many Singaporean citizens (Global Voices 2). These social concerns have, and still continue to, conflict the process of rapid gaming development in this growing country with much more economic influence today than in previous years. As previously identified, there are conflicting laws associated with casino gambling in this country. The Constitution clearly prohibits gambling in any format in the country, however representatives of the government c ontinue to amend the Constitution and create new, regionally-based policies that seek to overturn these prohibitions. However, such amendments require intervention with voting citizens both regionally and nationally-wide, again conflicting the process of securing long-term contracts and agreements for casino development and other associated hospitality organizations devoted to promoting tourism and economic growth. The Singapore conflicts associated with disparate laws and regulations illustrates a marked difference from
