Nucleus (center) and trailing uroid (upper left) of Amoeba proteus. To the right of the nucleus there are several food vacuoles. In addition many tiny crystals are visible.
Scale bar indicates 25 µm.
Higher magnification of cell zone with nucleus. Left the contractile vacuole (cv) and food vacuoles to the right of the cv. The nucleus shows his scattered nucluolus beneath the nuclear membrane (parietal arranged).
