Schematic presentation of pseudopodia and vacuolization processes in perforate foraminifera.
(A) The black cup represents the CaCO
3
shell which is exposed to the seawater. The letters
v,c,s,
and
p
,
represent vacuole, cytoplasm, symbionts and pseudopod, respectively. (B) The formation of a seawater
vacuole. (C) Self-vacuolization of the organism separating the shell from the environment. (D) Building of
a new chamber in a delimited space (
d
) with clear separation of intralocullar and extralocullar cytoplasm (
ic
and
ec
, respectively). The process of secondary lamination involves vacuolization of seawater. Arrows
represent seawater exchange in the delimited space.
