Chapter 32, Problem 6TYU
SCIENTIFIC INQUIRY • INTERPRET THE DATA Redraw the bilaterian portion of Figure 32.11 for the nine phyla in the table below. Consider these blastopore fates: protostomy (mouth develops from the blastopore), deuterostomy (anus develops from the blastopore), or neither (the blastopore closes and the mouth develops elsewhere). Depending on the blastopore fate of its members, label each branch that leads to a phylum with P, D, N, or a combination of these letters. What Is the ancestral blastopore fate? How many times has blastopore fate changed over the course of evolution? Explain.
| Blastopore Fate | Phyla |
| Protostomy (P) | |
| Deuterostomy (D) | Echinodermata, Chordata; most Arthropoda; few Mollusca, few Annelida |
| Neither (N) | Acoela |

Describe how metamorphosis changes the structures involved in gas exchange over the life cycle of animals in the clade Anura, and what evolutionary advantage this change provides.
Differentiate between Phylum Porifera and Clade Eumetazoa.
-Poriferans are only haploid during their life cycle, whereas eumetazoans are diploid with haploid sex cells at various stages of their life cycle.
-Poriferans have mobile gametes while eumetazoans do not.
-Poriferans invert during their development whereas eumetazoans do not invert at any time during their life cycle.
-The various cells types of Poriferans do not form permanent associations into true tissues during their life cycle, whereas Eumetazoa possess true, stable tissues.
-Poriferans have only one kind of cell during their life cycle whereas Eumetazoa have many kinds of cells throughout their life cycle.
