Phycology
Phycology () is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from the higher plants by a lack of true roots, stems or leaves. They do not produce flowers. Many species are single-celled and microscopic (including phytoplankton and other microalgae); many others are multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as kelp and '' Sargassum''). A number of microscopic algae also occur as symbionts in lichens. Phycologists typically focus on either freshwater or ocean algae, and further within those areas, either diatoms or soft algae. History of phycology While both the ancient Greeks and Romans knew of algae, and the ancient Chinese even cultivated certain varieties as food, the scientific study of alg ...

Botanist
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ...

Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

Flora
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and ...

Geranium Laxum
''Geranium'' is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, with the greatest diversity in the eastern part of the Mediterranean region. The palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple, or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring. Geraniums are eaten by the larvae of some Lepidoptera species including brown-tail, ghost moth, and mouse moth. At least several species of ''Geranium'' are gynodioecious. The species ''Geranium viscosissimum'' (sticky geranium) is considered to be protocarnivorous. Name The genus name is derived from Ancient Greek (''géranos'') ' crane'. The English na ...

New York Botanical Garden
The New York Botanical Garden (NYBG) is a botanical garden at Bronx Park in the Bronx, New York City. Established in 1891, it is located on a site that contains a landscape with over one million living plants; the Enid A. Haupt Conservatory, a greenhouse containing several habitats; and the LuEsther T. Mertz Library, which contains one of the world's largest collections of botany-related texts. , over a million people visit the New York Botanical Garden annually. NYBG is also a major educational institution, teaching visitors about plant science, ecology, and healthful eating through NYBG's interactive programming. Nearly 90,000 of the annual visitors are children from underserved neighboring communities. An additional 3,000 are teachers from New York City's public school system participating in professional development programs that train them to teach science courses at all grade levels. NYBG operates one of the world's largest plant research and conservation programs. NY ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

John Kunkel Small
John Kunkel Small (January 31, 1869 – January 20, 1938) was an American botanist. He studied plants in the southeastern United States and wrote a book about the deterioration of habitats in Florida. Early life and education Small was born on January 31, 1869, in Harrisburg, Pennsylvania, Harrisburg, Pennsylvania. He studied botany at Franklin & Marshall College, receiving his Bachelor's degree in 1892. Then he studied at Columbia University, where he earned a doctorate in philosophy in 1895 and a doctorate in science in 1912. Career After his first graduation in 1895, he became a special agent for the Georgia Geological Survey. Then, returning to Columbia University, he became the first Curator of Museums at the New York Botanical Garden, a post at which he served from 1898 until 1906.
