(A) Sponges belong to the Phylum $Porifera$. Their body organization includes $Ostia$ (pores for water entry),a central cavity called $Spongocoel$,and an internal skeleton made of $Spicules$ or $Spongin$ fibers. $Flame$ $cells$ (also known as $Protonephridia$) are specialized excretory cells found in Phylum $Platyhelminthes$ (flatworms),not in $Porifera$. Therefore,$Flame$ $cells$ are not present in sponges.
