An early endosome (ee) in planar view that contains
HRP-reaction product. This cell was exposed to HRP for 6 min. and then
fixed. This early endosome had two small coated evaginations arising
from its rim and also had two large HRP-containing uncoated vesicles
docked next to it presumably ready to fuse with it (for this picture
and a serial section showing these two vesicles and the second
evagination see Fig. 14C in Allen, Schroeder and Fok, J. Cell Sci.
101:449-461, 1992). Mitochondria (m) have an endogenous
peroxidase activity. tric, trichocyst. EM taken on 10/20/91 by
R. Allen with Zeiss 10A TEM. Neg. 19,800X. Bar = 0.25µm.
