Answer;
-Archaeocytes
Cells that move about in the mesohyl, digest particles, and may specialize for other functions are the archaeocytes.
Step-by-step explanation;
-Archaeocytes are very important to the functioning of a sponge. These cells are totipotent, which means that they can change into all of the other types of sponge cells.
-Archaeocytes ingest and digest food caught by the choanocyte collars and transport nutrients to the other cells of the sponge. In some sponges, archaeocytes develop into gametes.
