Patiria miniata
Biological Process
fertilization
Cellular Component
nuclear chromatin
Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...

Cellular Component
plasma membrane
This freeze fracture micrograph shows a region of membrane from the midpiece of opossum Didelphis virginiana sperm. This region of the sperm is notable for the repeating longitudinal bands composed ...

Cellular Component
male germ cell nucleus
Transmission electron micrograph of unstained cryo-section of a sperm cell of the starfish Patiria miniata. Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing the...

Cellular Component
plasma membrane
This electron micrograph shows the P-face of a small region of membrane from the midpiece of guinea pig sperm. The changing distribution of intramembranous particles (IMPs)in this image provided some...
