Q. Which of the following statements are true?
A) Phylum-Porifera-Presence of choanocytes and nematocysts
B) Phylum-Coelentrata-Meandrina belongs to this phylum
C) Phylum-Ctenophora-All exhibit bilateral symmetry
D) Phylum-Platyhelminthes-Wuchereria belongs to this phylum
Explanation
Phylum-Porifera have choanocyte cells but nematocyst is present in cnidoblasts cells and seen in animals that belong to phylum-Coelenterata. All ctenophora’s exhibit radial symmetry. Wuchereria belongs to phylum-Aschelminthes but Meandrina (also called brain coral) belongs to phylum-Coelenterata
