Spongilla Fragilis
Overview ''Spongilla'' is a genus of freshwater sponges with over 200 different species. Spongilla was first publicly recognized in 1696 by Leonard Plukenet and can be found in lakes, ponds and slow streams.''Spongilla'' have a leuconoid body form with a skeleton composed of siliceous spicules. They are sessile organisms, attaching themselves to hard substrate like rocks, logs and sometimes to ground. Using their ostia and osculum these sponges filter the water for various small aquatic organisms such as protozoans, bacteria, and other free-floating pond life. Sponges of the genus ''Spongilla'' partake in symbiotic relationships with green algae, zoochlorellae. The symbiotic zoochlorellae give the sponges a green appearance and without them they would appear white. ''Spongilla'' was used by John Hogg in the 19th century to attempt to justify a fourth kingdom of life. Reproduction Sponges are hermaphroditic organisms, producing both egg and sperm. Sperm is released from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spongilla Lacustris
''Spongilla lacustris'' is a species of freshwater sponge from the family Spongillidae. It inhabits freshwater rivers and lakes, often growing under logs or rocks. ''Lacustris'' is a Latin word meaning "related to or associated with lakes". The species ranges from North America to Europe and Asia. It is the most common freshwater sponge in central Europe. It is the most widespread sponge in Northern Britain, and is one of the most common species of sponges in lakes and canals. ''Spongilla lacustris'' have the ability to reproduce both sexually and asexually. They become dormant during winter. The growth form ranges from encrusting, to digitate, to branched, depending upon the quality of the habitat. Classification ''Spongilla lacustris'' is part of the class demosponges of the phylum Porifera. The Porifera phylum contains all sponges which are characterized by the small pores on the outer layer, which take in water. The cells in the sponge walls filter food from the water. Whate ...

Carolina Biological Supply Company
Carolina Biological Supply Company is a worldwide supplier of science education materials to teachers, college professors, home-school educators, and professionals in health and science-related fields. History Carolina was founded in 1927 by Dr. Thomas E. Powell Jr., a young geology and biology professor at Elon College (now Elon University). During the 1920s, science teachers had to collect most of the materials they used in their classes and laboratories, which took considerable time away from their primary responsibilities. Like other teachers, Dr. Powell spent much of his own time in the field gathering specimens for his classes. Because he usually got more than he needed, he sold the surplus to his colleagues. His efforts grew into Carolina Biological Supply Company, as Powell foresaw a need for his collecting abilities in the coming years. Products The company specializes in science materials for traditional K-12/college classrooms and labs. Its business units include Ca ...

Encyclopædia Britannica Online
An encyclopedia (American English) or encyclopædia (British English) is a reference work or compendium providing summaries of knowledge either general or special to a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on '' factual information'' concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.Béjoint, Henri (2000)''Modern Lexicography'', pp. 30–31. Oxford University Press. Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a v ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
