Brocchinioideae
''Brocchinia'' is a genus of the botanical family Bromeliaceae, and is the sole genus of the subfamily Brocchinioideae, containing 20 species. The genus is named for Giovanni Battista Brocchi, Italian naturalist (1772–1826). ''Brocchinia'' species are native primarily to the ancient Guayana Shield in southern Venezuela and Guyana, with some species extending into Colombia and northern Brazil. Its species are generally restricted to areas of sand and sandstone of the Roraima Formation; a few occur on granite.Givnish TJ, Burkhardt EL, Happel RE, Weintraub JW. 1985.

Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcairnioideae
Pitcairnioideae is a subfamily of the bromeliad family, Bromeliaceae. Traditionally, it was a large subfamily, comprising all those species with winged or more rarely naked seeds. Molecular phylogenetic studies showed that traditional Pitcairnioideae was not monophyletic, and the subfamily was more narrowly circumscribed. , the Encyclopaedia of Bromeliads placed five genera in the subfamily. Members of the subfamily are found from the Andes to the coast of Brazil, with one genus ('' Fosterella'') found northwards to Mexico. Description Species in the subfamily Pitcairnioideae have fruits in the form of capsules with winged seeds. The petals are not joined together when the flowers open, and are usually large and conspicuous. Taxonomy Traditionally, the family Bromeliaceae was divided into three subfamilies based on the structure of the seeds and fruit, with Pitcairnioideae comprising all those with winged or rarely naked seeds. The other subfamilies were Bromelioideae and Til ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyanobacterial Morphology
Cyanobacterial morphology refers to the form or shape of cyanobacteria. Cyanobacteria are a large and diverse phylum of bacteria defined by their unique combination of pigments and their ability to perform oxygenic photosynthesis. Cyanobacteria often live in colonial aggregates that can take a multitude of forms. Of particular interest among the many species of cyanobacteria are those that live colonially in elongate hair-like structures, known as trichomes. These filamentous species can contain hundreds to thousands of cells. They often dominate the upper layers of microbial mats found in extreme environments such as hot springs, hypersaline water, deserts and polar regions, as well as being widely distributed in more mundane environments. Many filamentous species are also motile, gliding along their long axis, and displaying photomovement by which a trichome modulates its gliding according to the incident light. The latter has been found to play an important role in guiding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epiphyte
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrmecophyte
Myrmecophytes (; literally "ant-plant") are plants that live in a mutualistic association with a colony of ants. There are over 100 different genera of myrmecophytes. These plants possess structural adaptations in the form of domatia where ants can shelter, and food bodies and extrafloral nectaries that provide ants with food. In exchange for these resources, ants aid the myrmecophyte in pollination, seed dispersal, gathering of essential nutrients, and defense. Domatia adapted specifically to ants may be called myrmecodomatia. Mutualism Myrmecophytes share a mutualistic relationship with ants, benefiting both the plants and ants. This association may be either facultative or obligate. Obligate In obligate mutualisms, the organisms involved are interdependent; they cannot survive on their own. An example of this type of mutualism can be found in the plant genus ''Macaranga''. All species of this genus provide food for ants in various forms, but only the obligate specie ...

Phosphatase
In biochemistry, a phosphatase is an enzyme that uses water to cleave a phosphoric acid Ester, monoester into a phosphate ion and an Alcohol (chemistry), alcohol. Because a phosphatase enzyme catalysis, catalyzes the hydrolysis of its Substrate (chemistry), substrate, it is a subcategory of hydrolases. Phosphatase enzymes are essential to many biological functions, because phosphorylation (e.g. by protein kinases) and dephosphorylation (by phosphatases) serve diverse roles in cell growth, cellular regulation and cell signaling, signaling. Whereas phosphatases remove phosphate groups from molecules, kinases catalyze the transfer of phosphate groups to molecules from Adenosine triphosphate, ATP. Together, kinases and phosphatases direct a form of post-translational modification that is essential to the cell's regulatory network. Phosphatase enzymes are not to be confused with phosphorylase enzymes, which catalyze the transfer of a phosphate group from hydrogen phosphate to an acce ...

Nectar
Nectar is a viscous, sugar-rich liquid produced by Plant, plants in glands called nectaries, either within the flowers with which it attracts pollination, pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal Mutualism (biology), mutualists, which in turn provide plant defense against herbivory#Indirect defenses, herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverfly, hoverflies, wasps, bees, butterfly, butterflies and moths, hummingbirds, honeyeaters and Bat#Fruit and nectar, bats. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of predacious or Parasitoid wasp, parasitoid wasps (e.g., the social wasp species ''Apoica flavissima'') rely on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
