AP Biology‚ Chapter 33 Invertebrates [by clade] SUMMARY INTRODUCTION PARAZOA Introduction Phylum Porifera: Sponges are sessile with porous bodies and choanocytes 1. Identify the parts of a sponge (including the spongocoel‚ porocyte‚ epidermis‚ choanocyte‚ mesohyl‚ amoebocyte‚ osculum‚ and spicule) and describe the function of each. a. Lifestyle: sessile‚ immobile filter feeders b. Water circulation i. Epidermis seals outside ii. Flagellated choanocytes lining

Due to the scope of our course‚ you are likely to see more general questions on individual phyla. For each of the phyla that we highlight in the questions that follow‚ try to know the characters that are

Because they are grouped in the same kingdom‚ the nine animal phyla share the same fundamental characteristics- they are multicellular‚ heterotrophic eukaryotes that obtain nutrients through ingestion‚ they lack cell walls‚ they have nervous tissue and muscle tissue‚ and they reproduce sexually and have a unique embryonic life cycle. However‚ the animal phyla have a great number of differences as well. Some are visible to the naked eye‚ while others are less obvious‚ and still more cannot even be

salinity. In addition the environment also undergoes daily tidal changes. By occupying these habitats‚ P. lucra and U. coarctata obviously tolerate a wide salinity range. However‚ it is anticipated that P. lucra being soft-bodied and related to annelids‚ tends towards osmoconforming; while U. coarctata‚ having a thick cuticle‚ tends towards osmoregulating over a range of salinities. This experiment is designed to test the hypothesis that P. lurcra is an osmoconformer and U. coarctata is an osmoregulator

leeches are found mainly in fresh water or on moist ground. Polychaeta: Bristle-worms - The marine worms are found chiefly in close vicinity of the shore. • OLIGOCHAETA = Earthworms • HIRUDINEA = Leeches • POLYCHAETA = Bristle-worms Some annelids are free-living‚ many inhabit burrows or dwell in tubes‚ some are commensals on other aquatic animals (few are ecto- or endoparasites)‚ and many of the leeches attach to vertebrates. • Symmetry bilateral.

allowing hemolymph fluid to flow among the cells. Most mollusks and arthropods have this type or system. In a closed circulatory system‚ the fluid is called blood and this fluid remains in the vessels as it circulates the body. Most vertebrates and annelids have this type of system. The purpose of this laboratory exercise was to demonstrate and explain the effects caffeine on the circulatory system of blackworms and to test the hypothesis that high concentrated caffeine will double the heart rate pulsation

CHAPTER NO-5 KINGDOM ANIMALIA Phylum Porifera (GK: Porous = Pores + Ferro = form) Main characters: 1. They are commonly called as sponges. 2. They are sessile animals. 3. Sponges range in height from about 1cm to 2cm. 4. More than 5000 species of sponges are found. 5. All are marine‚ while some are fresh water. 6. The central body cavity is called spongocoel. 7. A single large opening is called as osculum. 8. They are filter feeders. 9. Body lining is formed by flagellated cells

Answer: Monera- Single celled prokaryotes;bacteria Protista - Mostly single celled eukaryotes; Photoautotrophs (algae) and heterotrophs (protozoa) Fungi-Multicellular eukaryotes that feed by extracellular digestion and absorption Heterotrophs: includes decomposers‚ many pathogens and parasites Plantae-Multicellular photosynthetic autotrophs producers Animalia- Diverse multicellular heterotrophs Range from
