Euglossa Cordata
''Euglossa cordata'' is a primitively eusocial orchid bee of the American tropics. The species is known for its green body color and ability to fly distances of over 50 km. Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior. Because of this, sightings are rare and little is known about the species. However, it has been observed that adults who pollinate certain species of orchids will become intoxicated during the pollination. Taxonomy and phylogeny ''Euglossa cordata'' is a member of the genus '' Euglossa'' in the tribe Euglossini within subfamily Apinae of the hymenopteran family Apidae. ''Euglossini'' pollinate throughout the American tropics, and are known for their bright, metallic appearance. ''Euglossini'' is one of four tribes of the family Apinae, along with Meliponini (stingless bees), Bombini (bumble bees), and Apini (honey bees). There are five genera of Euglossini: '' Aglae'', '' Exaerete'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Euglossa Hyacinthina
''Euglossa hyacinthina'', is a species of the orchid bee Tribe (biology), tribe Euglossini in the family Apidae. With a tongue that can get up to as long as 4 cm, this orchid bee species is found in Central America. Living in a neotropical climate, ''E.'' ''hyacinthina'' has adapted to hot and humid weather. The bee has darkly shaded, translucent wings and a metallic, glossy blue skeleton. "Medium sized, large body stature, long-tongued, and fast," ''E. hyacinthina'' is characterized by its eusociality and unique solitary life-style. Additionally, this species has no worker or queen bees and females dominate in an atypical social hierarchy. The many individual nests of ''E. hyacinthina'' reveal the sociality of the bees, and the origin of this can be discovered by studying these nests. ''E. hyacinthina'' may also be part of mimicry complexes within ''Euglossa''. Taxonomy and phylogeny ''Euglossa'' is a genus of a larger tribe known as Euglossini, euglossine bees. Euglossin ...

Totipotent
Cell potency is a cell's ability to differentiate into other cell types. The more cell types a cell can differentiate into, the greater its potency. Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally unipotency. Totipotency Totipotency () is the ability of a single cell to divide and produce all of the differentiated cells in an organism. Spores and zygotes are examples of totipotent cells. In the spectrum of cell potency, totipotency represents the cell with the greatest differentiation potential, being able to differentiate into any embryonic cell, as well as any extraembryonic tissue cell. In contrast, pluripotent cells can only differentiate into embryonic cells. A fully differentiated cell can return to a state of totipotency. The conversion to totipotency is complex and not fully ... [...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] |
Corolla (flower)
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as '' Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they in ...

As noted by the position of the "bucket", liquid drops in from above by a special stem gland. The bucket fills, nectar drinking organisms such as bees are attracted to the sweet drops forming above the bucket. As the bees jostle for position, some bees inadvertently fall into the bucket. The bucket's fluid levels are regulated by a spout that allows overflowing liquid to be released. This is the only escape for the drowning bees.

Stanhopeinae
Stanhopeinae is a subtribe of plants in the tribe Cymbidieae. The subtribe in the strict sense, have viscidia and stipes that are thin and strap-like, they are adapted for attachment to edge of the bee's scutellum or to a leg. Pseudobulbs are usually ribbed/four-angled or flattened. Leaves are generally thicker than Coeliopsidinae. Roots are smooth, without prominent root hairs. The column foot is lacking or not distinct. Unpollinated flowers quickly abscise and fall from the inflorescence, unlike members of Coeliopsidinae which include ''Coeliopsis'', ''Lycomormium'', and ''Peristeria (plant), Peristeria''. Stanhopeinae and Coeliopsidinae are now considered closely related sister subtribes. Within Stanhopeinae the members can be further grouped in six clades based on morphological traits and molecular analysis. *''Braemia'' Clade: ''Braemia'' *''Gongora'' Clade: ''Cirrhaea'' & ''Gongora'' *''Acineta'' Clade: ''Acineta'', ''Lacaena'', ''Lueddemannia'' & ''Vasqueziella'' *''Polycy ...

Pollinaria
A pollinium (: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoideae, ( ...
