Figure 372 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. In the tapetum lucidum of a cat's eye, the cytoplasm of cells is filled with highly ordered rod-like ...

Electron micrographs show examples of pinocytosis in endothelial cells of blood vessels in the cat myocardium (panels A,B,C and H), and from the choroid rete of the bowfin fish eye. Both types of cell...

An electron micrograph of a potion of a cell of the unicellular alga Chlamydomonas reinhardii illustrating the eye spot, an organelle found inside the chloroplast that is composed of red carotenoid pi...

This is a live image of the bdelloid rotifer Philodina roseola under 20x magnification. Bdelloid rotifers are microscopic freshwater invertebrates best known for their capacity to undergo frequent cyc...

Light micrograph of volvox. Volvox are a relatively large (approximately 500 µm) green algae. They consist of hollow spherical colonies with up to 15,000 cells embedded in their gelatinous walls. E...
