Cladophora Albida

picture info	Cladophora Albida ''Cladophora'' is a genus of reticulated Hypha, filamentous Ulvophyceae (green algae). The genus ''Cladophora'' contains many species that are very hard to tell apart and classify, mainly because of the great variation in their appearances, which is affected by habitat, age and environmental conditions. Unlike ''Spirogyra'' the filaments of ''Cladophora'' branch and do not undergo conjugation. There are two multicellular stages in its life cycle – a ploidy, haploid gametophyte and a ploidy, diploid sporophyte – which look highly similar. The only way to tell the two stages apart is to either count their chromosomes, or examine their offspring. The haploid gametophyte produces haploid gametes by mitosis and the diploid sporophyte produces haploid spores by meiosis. The only visible difference between the gametes and spores of ''Cladophora'' is that the gametes have two flagellum, flagella and the spores have four. The ''Cladophora'' species can be a major nuisance causing majo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Friedrich Traugott Kützing Friedrich Traugott Kützing (8 December 1807 in Kalbsrieth, Ritteburg – 9 September 1893) was a German pharmacist, botanist and phycologist. Despite his limited background in regard to higher education, Kützing made significant scientific contributions. In 1833, he demonstrated differences between diatoms and desmids, thus separating the two groups into families of their own. Also, independent of Charles Cagniard-Latour (1777–1859) and Theodor Schwann (1810–1882), he was among the first to provide comprehensive answers in regard to yeast and the role it played in fermentation. In 1849, he published ''Species Algarum'', a massive work that provided descriptions for 6000 species of algae. He is the binomial authority, taxonomic authority of the genera ''Syringodium'' (family Cymodoceaceae) and ''Phlebothamnion'' (family Ceramiaceae). Early life As a young man, he worked in several pharmacies in Germany, also serving as assistant for a few semesters at the chemical-pharma ...

picture info	Mitosis In cell biology, mitosis () is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other. The process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next. These stages are preprophase (specific to plant cells), prophase ...
