TEM visualization of MTs in different algal cells: a chemical fixation protocol in Klebsormidium crenulatum visualizing cortical MTs in an adult cell. The arrows indicate the parallel orientation of the MTs. b plunge-frozen and freeze-substituted MTs in Micrasterias muricata. MTs in association with a migrating nucleus show various orientations in a MT organizing centre. Note the clear and sharp outer surfaces of the MTs. Bars, 0.2 µm
