Nucleus

Description:

Description: Amoeba with a pellicle-like surface noticeable by a rather stiff appearance and, in this case, numerous wrinkles. This image shows the nucleus at higher magnification (in the centre). It is spherical to ovoid, the nucleolus of granular texture, sometimes divided in 2 or 3 fragments. In the upper right corner a part of the contractile vacuole can be seen.  Modified Phase contrast.
