Which taxon is above phylum in classifying organisms? a. Kingdom b. Domain c. Class Use page 661 to answer the following: 5. Name the hollow ball that develops during embryo formation in animals? a. gastrula b. zygote c. blastula b. Safety Symbols and Statement (USE APPENDIX B on Page 1068) Fill in the blank for each symbol: Safety Statement: I am going to take the following precautions:

2 Station 1: Phylum Porifera 1. Examine the specimens. 2. Examine the life cycle sheet. 3. Draw and label specimens. 4. Using textbook, label the life cycle drawing below. Drawing of a specimens of Porifera What type of symmetry do porifera (sponges) have?

The phylum contains roundworms such as Ascaris. a. Platyhelminthes b. Nematoda c. Annelida 12. The phylum contain segmented worms such as leeches. a. Platyhelminthes b. Nematoda c. Annelida 13. Which type of metamorphosis has a nymph stage? a. Incomplete b. complete c. perfect 14. The phylum contains flatworms such as planaria. a. Platyhelminthes b. Nematoda c. Annelida 15. The kingdom that all animals are contained within? a. Eukarya b. Archaea c. Animalia

10 Use page 661 for reference for the question below. 1.What are the three cell layers that form during embryo during development. 2. Tell how these layers develop differently in protostomes and deuterostomes. Pick two phyla of invertebrates. Tell two characteristics that make them animals. Tell two differences that places them into different phylum.
