The family includes both fresh and marine aquatics and exhibits great diversity in form and habit including annual and perennial life histories; submersed, partially submersed and floating leaf habits and linear to orbicular leaf shapes. Ottelia, a typical example of aquatic plants, possesses extremely variable morphology and the presence of cryptic diversity makes its classification problematic. The family includes both fresh and marine aquatics and exhibits great diversity in form and habit including annual and perennial life histories; submersed, partially submersed and floating leaf habits and linear to orbicular leaf shapes. study of Animalia Kingdom) and Botany (i.e. Carolus Linnaeus (1707-1778) 4. Biology is one of the disciplines of science under which, we study about the various aspects of living organisms. A taxonomic revision of the genus Hydrilla (Hydrocharitaceae) is presented with a full description, diagnosis, synonyms with typifications, distribution maps and illustrations, also including information on ecology, floral biology, anatomy, embryology, chromosomes, genetics, variation and applied aspects with a rather extensive bibliography.Hydrilla is considered to be monotypic; however, … DISCUSSION Low salinity effects on Thalassia testudinum spectral reflectance measurements and indices. This record documents range expansion to the Caribbean mainland, and first observation of male flowers, of this introduced seagrass, which until April 2013 was only reported at several Caribbean islands. Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. Cancer cells are cause by uncontrolled cell growth, and other risk factors. Anther Initiation: The dynamics of anther development and differentiation depend on the co-operative interactions between cell populations. The anther lobes are fused together by the connective tissue […] Characters of Sapindaceae: Trees, shrubs or climbers usually pinnate leaves, the spring like circinately, coiled tendrils of lianous genera. In addition, the seagrass spectral reflectance changes at low salinities were comparable to changes measured in birch and fir under stress. Elodea plants are native to the New World, though a number of species have established themselves as invasive BIOLOGY DISCUSSION ASSIGMENT 4 1. Some Cells affected by breast cancer are cells that are lining the milk ducts. study of Plantae Kingdom). George Bentham (1800-1884) and Joseph Dalton Hooker’s (1817-1911) System. In its given premises, biology includes a wide range of topics such as physiology, morphology, anatomy, behavior, origin, distribution, etc. Theophrastus (370-287 BC) 2. Background. ADVERTISEMENTS: In this article we will discuss about the anatomy of anther. The anther normally consists of two lobes, each with two elongated microsporangia or pollen sacs. CELLS AFFECTED BY BREAST CANCER Brest cancer affects many men and woman around the world. Affinities. Broadly, Biology is categorized as Zoology (i.e. Distribution of Sapindaceae 3. Economic Importance 4. Previous studies have revealed cryptic Ottelia species in Asia, but very little is known … Elodea, genus of five or six species of submerged aquatic plants in the frog’s-bit family (Hydrocharitaceae), useful in aquariums and in laboratory demonstrations of cellular activities. Theophrastus (370-287 BC): He was a Greek naturalist and pupil of Plato and Aristotle. Characters of Sapindaceae 2. Revealing cryptic diversity is of great importance for effective conservation and understanding macroevolution and ecology of plants. The occurrence of the introduced seagrass Halophila stipulacea (Hydrocharitaceae) is reported for Puerto Azul, Playa Mansa, Venezuela. ADVERTISEMENTS: List of four eminent botanists who contributed to artificial system of plant classification:- 1. Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. John Ray (1627-1705) 3. ADVERTISEMENTS: In this article we will discuss about:- 1.
