Document Summary
Cell biology and genetics - notes on all lectures. Cell biology and genetics (university of technology, sydney) Discovered by robert (ooke ~ coined the term (cid:494)cell(cid:495). Cells are an organisms basic unit of structure and function. The cell is the lowest level of organisation that can perform all activities required for life. Division of cells ~ basis of reproduction, growth and repair. Cell size is limited ~ as size increases, it takes longer for material to diffuse from the cell membrane to the interior of the cell. Sa:v ratio ~ cell increases in size, volume increases 10x faster than. Certain structures in common: genetic material. Duplicator of information ~ dna replication enzymes. Information translator ~ ribosome: cytoplasm semifluid matrix, plasma membrane phospholipid bilayer. Taxonomy classifies species into groups of increasing breadth. These cells thrive almost everywhere, e. g. too acidic, salty, cold or hot.
