Standard 11-A Classify animals according to type of skeletal structure and method of fertilization and reproduction body symmetry, body coverings, and PowerPoint by: location. Quenton Mercedes The eligible content • • • • • Compare Compare Compare Compare Compare invertebrates to vertebrates. endoskeletons to exoskeletons internal to external fertilization. sexual to asexual reproduction. bilateral to radial symmetry. COMPARE INVERTEBRATES TO VERTEBRATES Vertebrates and Invertebrates. Vertebrates and Invertebrates • Vertebrates are • Invertebrates are animals with backbones (shown in the last slide) these include: fish, mammals, amphibians, birds, and reptiles animals without backbones these animals include insects and mollusks & sponges. What is an endoskeleton? What is an endoskeleton? • An endoskeleton is an internal supporting system. All vertebrates have an endoskeleton. Their skeleton is on the inside. Endo – means inside What is an exoskeleton? is anis aexoskeleton? •What An Exoskeleton skeleton or supporting structure that is found on the OUTSIDE of the animal. • An Exoskeleton is like armor on the outside • These animals include: insects, crustaceans like crabs & lobster, and sea stars. Endotherms & Ectotherms • Endotherms – are warm blooded ( they • • maintain their body temperatures from INSIDE their bodies. Endo – means inside Mammals, & birds are the only endothermic animals • Ectotherms – are cold blooded ( they get their body heat from the outside world) What are Asexual & Sexual reproduction? • Asexual reproduction is when an organism has only ONE parent; Usually a part of a parent splits off to from another organism. • Sexual reproduction- the cells of 2 different parents unite to form the new organism. (Not meaning that the parents have sex ).This type makes the offspring more diverse What is internal and external fertilization? • Internal fertilization - the egg is fertilized inside the female • External fertilization - the male and female sex cells come together outside the female’s body. Compare bilateral and radial symmetry Bilateral and radial symmetry • Bilateral symmetry • Radial symmetry• If you divide the each part that animal in half, one side is just like the other side radiates from a central point is alike. Bilateral Symmetry Pictures If divided down the middle, one half is just like the other half. Radial Symmetry Pictures Question Time Which characteristic are used to determine the classification of a sea star? A. Radial symmetry and an exoskeleton B. Radial symmetry and an endoskeleton C. Bilateral symmetry and an exoskeleton D. Bilateral radial symmetry and an endoskeleton The answer is ……. A. Radial symmetry and exoskeleton, because it has a hard outer skeleton and radiating parts A new organism is discovered. After careful observation, scientists conclude that it is a mammal. Which 2 characteristics would the organism possess? A. Endoskeleton and scales B. Exoskeleton and asymmetry C. Fur or hair & warm- blooded & endoskeleton D. Have live young and radial symmetry The answer is…. C. Fur or hair and warm blooded & an endoskeleton. These are all characteristics of mammals Study the table below. Which organism is MOST LIKELY to a clam? organism support respiration habitat 1 endoskeleton Gills, skin aquatic 2 shell gills aquatic 3 endoskeleton Lungs, skin terrestrial 4 shell lungs terrestrial And the answer is...... • Organism 2- because it has a shell which is exoskeleton it has gills which allows it to live in the water. Which animal ‘s body shape show bilateral symmetry? • A. Jellyfish • B. sea anemone • C. fish • D. sea anemone And the answer is ….. • C- fish because when you cut the fish down the middle the sides are equal. Which group of animals contains members that move using cilia and flagella? • A. birds • B. protists • C. mammals • D. amphibians And the answer is ….. • B- protists • cilia is a hair like structures and a flagella has a whip- like tail and protists have both of these Which animal has external fertilization? • A. human • B. frog • C. snakes • D. whales And the answer is….. •B Frogs • Their eggs are fertilized OUT side of their bodies. Which sea animal has radial symmetry? • A. Echinoderms (like star fish) • B. Lobsters • C. Whales • D. Humans And the answer … •A. Echinoderms – their legs all RADIATE out from the center Which animal is a vertebrate? • A. Reptile • B. clam • C. scallop • D. sponge And the answer is …. • A. reptile because it has an internal backbone A is correct • Sea stars have radial symmetry & their skeleton is on the outside ( exoskeleton) D. Student 4 was correct • Amphibians ( frogs) have moist skin & are cold blooded (ectotherms) C is correct • Sharks have cartilage skeletons & eels have skeletons made of bone B. organism 2 is a clam • Clams have a shell, gills to breath and are aquatic ( live in the water) A. Student 1 Which animal has an exoskeleton? • A. bony fish • B. crustacean (like crabs & lobster) • C. reptile • D. birds And the answer is….. • B. crustacean because it has an hard outer structure Which animal does NOT have external fertilization? • A. clams • B. humans • C. sponges • D. insects Hint: Decide what the question IS asking. It IS asking about the animal that has Internal Fertilization. And the answer is… •A. Humans • Humans have internal fertilization (the egg & sperm come together INSIDE the female) • When a question asks which one does NOT do something, then figure out what you are looking for Which of the following means internal supporting system (skeleton)? •A. external fertilization •B. exoskeleton •C. radial symmetry •D. endoskeleton And the answer is… • D. endoskeleton because the skeleton is found on the inside of the organism C. The fish • If you cut the fish in half down the middle one side is just like the other side C. Flagella are used for locomotion What is an invertebrate? • A. bird • B. human • C. dog • D. clam And the answer is… • D. clam because it does not have a backbone or a spinal column
