Thallus Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs.

Tardigrades (Water Bears) Tardigrades (Tardigrada), also known as water bears or moss piglets, are a phylum of small invertebrates. They were first described by the German pastor J.A.E. Goeze in 1773 and given the name Tardigrada, meaning slow stepper, three years later by the Italian biologist Lazzaro Spallanzani. Tardigrades are short (0.05mm - 1.2mm in body length), plump, bilaterally symmetrical, segmented organisms.

Classification The loggerhead sea turtle belongs to the order Testudines (NOAA, 2013). Testudine is the order of reptiles that has 260 living species of turtles and tortoises. Turtles and tortoises, or testudines, are different from other reptiles because they do not have holes in the side of the skull.oggerhead sea turtles belong to the subphylum Vertebrata, which stems from the Latin root vertebra meaning a joint or backbone (Duermit, 2007; Guill, 1960). Characteristics of the subphylum vertebrata are that all the organisms have a vertebral column that is a main skeletal structure along the length of its body.

Dictyostelium discoideum Dictyostelium discoideum is a species of soil-living amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa. Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.rogrammed cell death (apoptosis) is a normal part of species development. Apoptosis is necessary for the proper spacing and sculpting of complex organs. Around 20% of cells in D. discoideum altruistically sacrifice themselves in the formation of the mature fruiting body.

Vegetative Organs In lower plants, the vegetative body (thallus) is not separated into organs but consists of a single cell (in unicellular algae, lower fungi); of threads formed from one layer of cells (in filamentous algae, mycelium of fungi): or of colonies in the form of plates, globes, and the like.

Marchantia polymorpha Description [edit]. It is a thallose liverwort which forms a rosette of flattened thalli with forked branches. The thalli grow up to 10 cm long with a width of up to 2 cm. It is usually green in colour but older plants can become brown or purplish. The upper surface has a pattern of hexagonal markings. The underside is covered by many root-like rhizoids which attach the plant to the soil.

Sponge Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/ ; meaning pore bearer). They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.he simplest body structure in sponges is a tube or vase shape known as asconoid, but this severely limits the size of the animal. The body structure is characterized by a stalk-like spongocoel surrounded by a single layer of choanocytes.

Thallium Thallium is a chemical element with symbol Tl and atomic number 81. This soft gray post-transition metal is not found free in nature. When isolated, it resembles tin, but discolors when exposed to air.hallium is extremely soft, malleable and sectile enough to be cut with a knife at room temperature. It has a metallic luster that, when exposed to air, quickly tarnishes to a bluish-gray tinge, resembling lead. It may be preserved by immersion in oil. A heavy layer of oxide builds up on thallium if left in air.

Turbidite turbidites. Turbidites are sea-bottom deposits formed by massive slope failures where rivers have deposited large deltas. These slopes fail in response to earthquake shaking or excessive sedimentation load.urbidites (interbedded with mudstones/siltstones) from the Ross Sandstone Formation Turbidite system of Namurian age in County Clare, Western Ireland. The sandstone beds were formed in a deep basin by turbidites coming from a delta area.

- Diatoms are delicate unicellular organisms that have a yellow-brown chloroplast that enables them to photosynthesize. Their cell walls are made of silica almost like a glass house. The construction of the cell wall, called the frustule, consists of two valves that fit into each other like a little pill box.iatoms are delicate unicellular organisms that have a yellow-brown chloroplast that enables them to photosynthesize.

Zooid The zooids can either be directly connected by tissue (e.g. corals, Catenulida, Siphonophorae, Pyrosome or Ectoprocta) or share a common exoskeleton (e.g. Bryozoa or Pterobranchia). The colonial organism as a whole is called a zoon /ˈzoʊ.ɒn/, plural zoa (from Greek zòon ζώον meaning animal; plural zòa, ζώα).

Environmental and Gut Bacteroidetes: The Food Connection The phylum Bacteroidetes is a very diverse bacterial phylum, the name of which changed several times over the past years. It is also known as the Cytophaga–Flexibacter–Bacteroides (CFB) group, an appellation that reflects the diversity of organisms found in this phylogenetic group (Woese, 1987; Woese et al., 1990).

Thallium Thallium is a chemical element with symbol Tl and atomic number 81. This soft gray post-transition metal is not found free in nature. When isolated, it resembles tin, but discolors when exposed to air.hallium is found in the minerals crookesite TlCu 7 Se 4, hutchinsonite TlPbAs 5 S 9, and lorandite TlAsS 2. Thallium also occurs as a trace element in iron pyrite, and thallium is extracted as a by-product of roasting this mineral for the production of sulfuric acid.
