Rhynchostegium Serrulatum
''Rhynchotegium serrulatum'' is a species of moss in the Brachytheciaceae family. It is mainly distributed throughout the Americas. ''Rhynchotegium serrulatum'' is known to be able to use artificial light to grow in places which are otherwise devoid of natural light, such as Niagara Cave Niagara Cave is a limestone cave located in Harmony, Minnesota. The cave is approximately 200 feet (61 m) deep; features include an underground stream, 60-foot waterfall, fossils, stalactites and stalagmites. The cave is privately owned, with ....

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Brachytheciaceae
Brachytheciaceae is a family of mosses from the order Hypnales. The family includes over 40 genera and 250 species. Description The family consists of pleurocarpous mosses with very diverse appearances. They are irregular or pinnately branched and form loose mats. The leaves are broad ovate or triangular and are sharply focused at the top. A midrib is always present and usually reaches more than half of the leaf. The leaf cells are prosenchymatous and are many times longer than wide and interlocking with pointed ends. The sporophyte consists of a regularly formed spore capsule that stands straight on the setae. The spores are distributed through an annular peristome, which is closed off by a beak-shaped operculum in immature plants. Habitat Species are terrestrial, epiphytic, or lithophytic plants that are distributed around the world. They grow on various substrates, including rock, bark, and soil. Taxonomy Brachytheciaceae is in the order Hypnales. They are a sister group ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Artificial Light
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects. History With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 years ago, fire was kindled ...

Niagara Cave
Niagara Cave is a limestone cave located in Harmony, Minnesota. The cave is approximately 200 feet (61 m) deep; features include an underground stream, 60-foot waterfall, fossils, stalactites and stalagmites. The cave is privately owned, with tours available seasonally. The cave was first discovered in 1924, and in 1932, three spelunkers Al Cremer, Leo Tekippe, and Joe Flynn explored the cave and named the site Niagara Cave. Niagara Cave opened as a show cave in June 1934, and was described by geologist J Harlen Bretz in 1938. The Minnesota Geological Survey The Minnesota Geological Survey is a unit of the Newton Horace Winchell School of Earth Sciences at the University of Minnesota The University of Minnesota, formally the University of Minnesota, Twin Cities, (UMN Twin Cities, the U of M, or ... noted in their 1995 survey, "Niagara Cave contains an excellent example of an underground river, complete with waterfall."
