The mode of digestion?

To answer the question
Due to their excessively primitive
anatomy, the digestive process of porifera seems inferior.
However, through further interpretation , it may be perceived
as almost remarkable. Mother Nature compensated for the
anatomical deficiencies of sponges through the conception
of archaeocytes. Sometimes, food is transmitted
to the sponge by algae or other organisms living within
the sponge. However, beyond a doubt, archaeocytes
are one of the most fascinating features of sponges. They
are also one of the primary body parts asscoiated with digestion.
Due to ocean currents, water is absorbed through the same
protocol implemented in respiration. Currents create
low pressure above the incurrent ducts (pinacocytes, porocytes,
etc), and the water is drawn in. Once through incurrent
ducts, microscopic particles are captured by the choanoflagellates.
Surprisingly, these collared cells have been theorized to
evolve from an almost insignificant division of protists.
Water is subsequently conducted through canal systems and
the osculum. Food that was extracted by the choanoflagellates
is partially consumed by these cells in the proximity of
the flagellates. However, to ensure the efficiency of the
system, archaeocytes come into play. Archaeocytes are essential
for the survival and prosperity of porifera. Without them,
sponges would be even less complex and unable to survive.
Inherently, archaeocytes may perform any plethora of tasks
that is required of them from reproduction to growth to
regeneration. In addition, they transport resources throughout
the entire organism to enable its development. How do they
do it? The world may never know!!
