Biologie (z řeckého bio jako život a logie jako věda – tedy životověda – věda zkoumající život) v nejširším slova smyslu je vědní obor zabývající se organismy a vším, co s nimi souvisí, od chemických dějů v organismech probíhajících na úrovni atomů a molekul, až po celé ekosystémy.. V užším slova smyslu bychom pak biologii mohli popsat jako vědu ...

Строение. Красные водоросли — эукариоты.Хлоропласты красных водорослей двумембранные, с одиночными тилакоидами.Один или два тилакоида обычно лежат на периферии хлоропласта.

Heterokonts are a group of protists (formally referred to as Heterokonta, Heterokontae or Heterokontophyta).The group is a major line of eukaryotes. Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton.Other notable members of the Stramenopiles include the (generally) parasitic oomycetes, including …

Pluriformea is a proposed sibling clade of the Filozoa, and consists of Syssomonas multiformis and the Corallochytrea.Together with the Ichthyosporea they form the Holozoa.. An up to date cladogram is

Gli eucarioti (Eukaryota, dal greco εὖ eu «buono» e κάρυον káryon «nucleo») sono uno dei due domini della classificazione tassonomica degli esseri viventi.Costituiscono il dominio più complesso e includono cinque regni: piante, funghi, animali, protisti e cromisti.. Il criterio per la distinzione dall'altro dominio, i procarioti, è la presenza di un nucleo cellulare ben ...

Significance. They are not particularly distinctive morphologically, appearing in host tissues as enlarged spheres or ovals containing spores, and most were originally classified in various groups as fungi, protozoa, or colorless algae.However, they form a coherent group on molecular trees, closely related to both animals and fungi and so of interest to biologists studying their origins.

Typically, the cell is divided transversally, with the anterior half of the ciliate (the proter) forming one new organism, and the posterior half (the opisthe) forming another.However, other types of fission occur in some ciliate groups. These include budding (the emergence of small ciliated offspring, or "swarmers", from the body of a mature parent); strobilation (multiple divisions …

Basidiomycota (/ b ə ˌ s ɪ d i. oʊ m aɪ ˈ k oʊ t ə /) is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi.Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly ...

Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In traditional and currently no longer supported classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa. In the classification …

The opisthokonts (from Ancient Greek ὀπίσθιος (opísthios) 'rear, posterior', and κοντός (kontós) 'pole, i.e. flagellum') are a broad group of eukaryotes, including both the animal and fungus kingdoms. The opisthokonts, previously called the "Fungi/Metazoa group", are generally recognized as a clade.Opisthokonts together with Apusomonadida and Breviata comprise the …
