Answer:
Correct Answer: C
Solution:
The cell aggregate plan refers to a body plan wherein the body contains a cluster or aggregation of cells that are not organized into cells or organs.
The phylum porifera’s members have a cell aggregate body plan.
Sponges are the generic term for these.
They are also renowned as ‘pore-bearers,’ because of the many tiny pores on their body wall.
All sponges are planktonic; the majority are marine, but just a few species, such as spongilla, are freshwater.
