Answer:
Porifera—gastrovascular cavity, coelomate.
Explanation:
Sponges do not contain digestive system but obtain nutrients through the diffusion process. Porifera is the most commonly asymmetrical in nature but can also have radial symmetry. Porifera has no coelom.
Lacking a true digestive system, they depend on the intracellular digestive processes of their choanocytes for their energy intake. Gas exchange, circulation, and excretion occur by diffusion between the water and the cells.
Answer:
Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.
Explanation:
Ribosome Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s
Cell wall Prokaryotes such as bacterial cell contain cell wall.Cell wall of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.
Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.
Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.
