Biology is one of the disciplines of science under which, we study about the various aspects of living organisms. George Bentham (1800-1884) and Joseph Dalton Hooker’s (1817-1911) System. ADVERTISEMENTS: In this article we will discuss about:- 1. Some Cells affected by breast cancer are cells that are lining the milk ducts. In addition, the seagrass spectral reflectance changes at low salinities were comparable to changes measured in birch and fir under stress. 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. Affinities. In its given premises, biology includes a wide range of topics such as physiology, morphology, anatomy, behavior, origin, distribution, etc. Ottelia, a typical example of aquatic plants, possesses extremely variable morphology and the presence of cryptic diversity makes its classification problematic. Background. 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. Revealing cryptic diversity is of great importance for effective conservation and understanding macroevolution and ecology of plants. Theophrastus (370-287 BC) 2. ADVERTISEMENTS: In this article we will discuss about the anatomy of anther. Broadly, Biology is categorized as Zoology (i.e. Economic Importance 4. CELLS AFFECTED BY BREAST CANCER Brest cancer affects many men and woman around the world. Carolus Linnaeus (1707-1778) 4. BIOLOGY DISCUSSION ASSIGMENT 4 1. The family has a cosmopolitan distribution … 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. Elodea plants are native to the New World, though a number of species have established themselves as invasive 1. 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. Our hypothesis of significant change in spectral reflectance caused by lowered salinities was confirmed. Botanist # 1. Characters of Sapindaceae: Trees, shrubs or climbers usually pinnate leaves, the spring like circinately, coiled tendrils of lianous genera. John Ray (1627-1705) 3. Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. The anther lobes are fused together by the connective tissue […] study of Plantae Kingdom). Characters of Sapindaceae 2. Anther Initiation: The dynamics of anther development and differentiation depend on the co-operative interactions between cell populations. Theophrastus (370-287 BC): He was a Greek naturalist and pupil of Plato and Aristotle. 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. 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, … Distribution of Sapindaceae 3. Based on […] Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. The anther normally consists of two lobes, each with two elongated microsporangia or pollen sacs. Cancer cells are cause by uncontrolled cell growth, and other risk factors.
