Introduction to Animal Kingdom

CH 24 WHAT IS AN ANIMAL? CHARACTERISTICS OF ALL ANIMALS Eukaryotic Multicellular Specialized cells (tissues & organs) Ingestive heterotrophs 1.5 million.

Animal Characteristics Heterotrophs – must ingest others for nutrients Multicellular – complex bodies No cell walls – allows active movement Sexual reproduction.

Animal Kingdom Notes Part I. Basics! Vertebrate – has a backbone –FEEL YOURS! Invertebrate – no backbone (simpler animals)

The Animal Kingdom Heterotrophic by ingestion

ANIMAL KINGDOM CLASSIFICATION Animals can be grouped into two large categories: Vertebrates and Invertebrates. Vertebrates have backbones and invertebrates.

Invertebrate Review AP Biology

What is the germ layer in embryological development that will form the skin and nervous system? ECTODERM

What is the name of the organism whose gut development follows this pattern? PROTOSTOME

What is the name of a fluid-filled body cavity that characterizes animals? COELOM

How would we characterize this organism in terms of body cavity? ACOELOMATE

Which of the following characteristics is NOT present in all animal phyla? multicellularity organ systems heterotrophy diploidy sexual reproduction

What is the term for the development of nervous tissue and sensory organs towards a localized “head” region? CEPHALIZATION

How do poriferans (sponges) feed? FILTER FEEDING

What is the name of the structure in sponges that provides skeletal support and is made of silica or calcium carbonate? SPICULE

What is this structure, which allows water to pass through the sponge? PORE

Which phylum is characterized by radial symmetry and two germ layers? CNIDARIA

What are the names of the two body forms a cnidarian may take? MEDUSA & POLYP

What is this structure? (which can really sting if you trigger it!) NEMATOCYST

Which phylum is better known as the flatworms? PLATYHELMINTHES

Tissues derived from mesoderm are absent in sponges. cnidarians. flatworms. sponges and cnidarians. sponges, cnidarians, and flatworms.

Which of the following is mismatched? cnidarians; nematocysts sponges; spicules flatworms; bilateral symmetry annelids; segmented body echinoderms; protostomes

Which phylum contains a mantle? MOLLUSCA

What structure in mollusks is responsible for feeding? RADULA

Within phylum Mollusca, under what class does this organism fall? CEPHALOPODA

NEMATODA What phylum does this describe? Flexible cuticle, longitudinal muscles, a complete digestive system, and a false coelom. NEMATODA

Which phylum is characterized by being the first to have segmentation? ANNELIDA

What is the name of the structure in arthropods that provides physical support, protection, must be shed, prevents drying out, and is an anchoring site for muscles? EXOSKELETON

A water vascular system is characteristic of which phylum? ECHINODERMATA

All EXCEPT which of these is an echinoderm? sea anemone sea lily sea urchin brittle star sand dollar
