The cell was a container for protoplasm, the fundamental and universal material substance of life. Huxley's principal contribution was to establish protoplasm as incompatible with a vitalistic theory of life. [51] Attempts to investigate the origin of life through the creation of synthetic "protoplasm" in the laboratory were not successful. [52]
In 1938, Fischer and Suer proposed that water in the protoplasm is not free but in a chemically combined form—the protoplasm represents a combination of protein, salt and water—and demonstrated the basic similarity between swelling in living tissues and the swelling of gelatin and fibrin gels. Dimitri Nasonov (1944) viewed proteins as the ...
He developed an experimental science called plasmogeny, concerned with the origin of protoplasm, the living material of which all animals and plants are made.He reasoned that since life was the result of purely physico-chemical phenomena, it should be possible to create a structure with similar properties to natural protoplasm out of relatively simple organic and inorganic compounds in the ...
Haeckel had theorized about Urschleim ("primordial slime"), a protoplasm from which all life had originated. Huxley thought Bathybius could be that protoplasm, a missing link (in modern terms) between inorganic matter and organic life. Huxley published a description of Bathybius that year [1] and also wrote to Haeckel to tell him about it ...
He recognized under the name of primordial utricle the protoplasmic lining of the vacuolated cell, and first described the behaviour of the protoplasm in cell division. These and other observations led to the overthrow of Schleiden's theory of origin of cells by free-cell-formation. His contributions to knowledge of the cell-wall were no less ...
Protoplasts of cells from a petunia's leaf Protoplasts of the moss Physcomitrella patens. Protoplast (from Ancient Greek πρωτόπλαστος (prōtóplastos) 'first-formed'), is a biological term coined by Hanstein in 1880 to refer to the entire cell, excluding the cell wall.
