Desmid Micrasterias, a chlorophyceae alga of extraordinary beauty, beginning to divide. Micrasterias have bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing th...

Upon electron bombardment, some elements, such as P, show an electron energy loss profile with a peak at a specific energy loss value. By collecting a series of images of a field at different energy l...

Figure 316 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The differences in size and shape of cilia and microvilli are well illustrated by scanning micrographs of the lumen...

Figure 326 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. Cells of sense organs detecting vibration are provided with stiff surface projections, the size of cilia but lackin...
