An enlargement of the left pronucleus in Figure 10. The chromatin
material appears as sparsely scattered opaque bodies, as may be
expected of a haploid nucleus, in a medium dense nucleoplasm. The
nuclear envelope of the pronucleus seems to be in very close contact
with the nuclear envelope of the macronucleus (arrow) as though
pores might link and allow direct communication between the two
nuclei. Remnants of microtubules are scattered in the nucleoplasm. EM
taken on 3/4/80 by R. Allen with Hitachi HU11A TEM. Neg. 10,250X. Bar
= 0.5µm.
