Document Summary
1670"s anton van leeuwenhoek, made many microscopes and looked at everything! All organisms composed of one or more cells. The cell is the structural unit of life: 1855, virchow, added: cells can only arise by division from a pre-existing cell. There are 1000 microns ( m) in 1 mm. Most eukaryotic cells are between10 and 100 microns ( m) Most prokaryotic cells are about 5 microns ( m) Regulates protein traffic and performs metabolic functions in cell. Have nuclear pores, stuff goes in and out. Nuclear pores facilitate movement, allows only certain things to enter. Made of lamin proteins, give shape and stability. Function: protein synthesis: large and small subunits, rrna and protein. Free in cytosol, attached to membranes (er and nucleus). Golgi functions: a cisternae comprises a flattened membrane disk that makes up the golgi apparatus. Manufacturing/modifying (add sugars: sorting, storing, shipping cisternal maturation model. Cisternae is formed off th er, vesicles bud off.
