Vacuoles in fungal cells perform similar functions to those in plants and there can be more than one vacuole per cell. In yeast cells the vacuole ( Vac7 ) is a dynamic structure that can rapidly modify its morphology .
Toxic vacuolization. A vacuolated neutrophil. Specialty. Hematology. Causes. Sepsis, bacterial infection, alcohol toxicity, liver failure, G-CSF treatment. Toxic vacuolation, also known as toxic vacuolization, [1] is the formation of vacuoles in the cytoplasm of neutrophils in response to severe infections or inflammatory conditions. [2][3]
The contractile vacuole acts as part of a protective mechanism that prevents the cell from absorbing too much water and possibly lysing (rupturing) through excessive internal pressure. The contractile vacuole, as its name suggests, expels water out of the cell by contracting. The growth (water gathering) and contraction (water expulsion) of the ...
Paraptosis (from the Greek παρά para, "related to" and apoptosis) is a type of programmed cell death, morphologically distinct from apoptosis and necrosis. The defining features of paraptosis are cytoplasmic vacuolation, independent of caspase activation and inhibition, and lack of apoptotic morphology.
Ciliates are an important group of protists, common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils, including anoxic and oxygen-depleted habitats. [2] About 4,500 unique free-living species have been described, and the potential number of extant species is estimated at 27,000–40,000. [3]
An amoeba (/ əˈmiːbə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / əˈmiːbi /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods. [2] Amoebae do not form a single taxonomic ...
Along with Döhle bodies and toxic vacuolation, which are two other findings in the cytoplasm of granulocytes, toxic granulation is a peripheral blood film finding suggestive of an inflammatory process. [1] Toxic granulation is often found in patients with bacterial infection and sepsis, [1][2] although the finding is nonspecific. [3]
In most bacteria the most numerous intracellular structure is the ribosome, the site of protein synthesis in all living organisms. All prokaryotes have 70S (where S= Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits.
