An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination.
Endoplasm generally refers to the inner (often granulated), dense part of a cell's cytoplasm.
The endoplasmic reticulum (ER) is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae.
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike Prokaryotes (Bacteria and other Archaea).
In scientific research, an experimental system is the physical, technical and procedural basis for an experiment or series of experiments.
Félix Dujardin (5 April 1801 – 8 April 1860) was a French biologist born in Tours.
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the gram-staining method of bacterial differentiation.
Ground substance is an amorphous gel-like substance in the extracellular space that contains all components of the extracellular matrix except for fibrous materials such as collagen and elastin.
Hugo von Mohl FFRS HFRSE (8 April 1805 – 1 April 1872) was a German botanist from Stuttgart.
An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).
Jan Evangelista Purkyně (also written Johann Evangelist Purkinje) (17 or 18 December 1787 – 28 July 1869) was a Czech anatomist and physiologist.
Johannes Ludwig Emil Robert von Hanstein (15 May 1822 – 27 August 1880) was a German botanist who was a native of Potsdam.
Julius von Sachs (2 October 1832 – 29 May 1897) was a German botanist from Breslau, Prussian Silesia.
Lev Semyonovich Tsenkovsky (Leon Cienkowski, Лев Семенович Ценковский) (October 1 (N.S. October 13), 1822 in Warsaw – September 25 (N.S. October 7), 1887 in Leipzig) was a Polish-Ukrainian botanist, protozoologist, bacteriologist, who was mostly active in Ukraine, then part of the Russian Empire.
Lionel Smith Beale (5 February 1828 – 28 March 1906) was a British physician, microscopist, and professor at King's College London.
In biology and biochemistry, a lipid is a biomolecule that is soluble in nonpolar solvents.
Lorenz Oken (1 August 1779 – 11 August 1851) was a German naturalist, botanist, biologist, and ornithologist.
A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers).
Materialism is a form of philosophical monism which holds that matter is the fundamental substance in nature, and that all things, including mental aspects and consciousness, are results of material interactions.
A membrane is a selective barrier; it allows some things to pass through but stops others.
A metaplasm is a change in the orthography (and hence phonology) of a word.
In cell biology, microsomes are vesicle-like artifacts re-formed from pieces of the endoplasmic reticulum (ER) when eukaryotic cells are broken-up in the laboratory; microsomes are not present in healthy, living cells.
Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations.
Monosaccharides (from Greek monos: single, sacchar: sugar), also called simple sugars, are the most basic units of carbohydrates.
Nucleic acids are biopolymers, or small biomolecules, essential to all known forms of life.
Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm, karyoplasm, or nucleus sap.
In cell biology, an organelle is a specialized subunit within a cell that has a specific function, in which their function is vital for the cell to live.
Johann Adam Otto Bütschli (3 May 1848 – 2 February 1920) was a German zoologist and professor at the University of Heidelberg.
The periplasm is a concentrated gel-like matrix in the space between the inner cytoplasmic membrane and the bacterial outer membrane called the periplasmic space in gram-negative bacteria.
The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a double-membrane organelle found in the cells of plants, algae, and some other eukaryotic organisms.
Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages, and on hydrolysis give the constituent monosaccharides or oligosaccharides.
