cell mechanics









































cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. it encompasses aspects of cell biophysics, biomechanics, soft matter physics and rheology, mechanobiology and cell biology.









































section::::eukaryotic cell mechanics.









































eukaryotic cells are cells that consist of membrane-bound organelles, a membrane-bound nucleus, and more than one linear chromosome. being much more complex than prokaryotic cells, cells without a true nucleus, eukaryotes must protect its organelles from outside forces.

the first model known as the "syntrophic model" proposes that a symbiotic relationship between the archaea and bacteria created the nucleus-containing eukaryotic cell. (organisms of the archaea and bacteria domain have no cell nucleus.) it is hypothesized that the symbiosis originated when ancient archaea, similar to modern methanogenic archaea, invaded and lived within bacteria similar to modern myxobacteria, eventually forming the early nucleus. this theory is analogous to the accepted theory for the origin of eukaryotic mitochondria and chloroplasts, which are thought to have developed from a similar endosymbiotic relationship between proto-eukaryotes and aerobic bacteria. the archaeal origin of the nucleus is supported by observations that archaea and eukarya have similar genes for certain proteins, including histones. observations that myxobacteria are motile, can form multicellular complexes, and possess kinases and g proteins similar to eukarya, support a bacterial origin for the eukaryotic cell.
