OBJECTIVE 5.0 and 5.3 Identify the major internal and external structures, methods of locomotion, methods of reproduction, and stages of development of animals.
GENERAL INFORMATION • HETEROTROPHS THAT MOSTLY MOVE TO GET FOOD • 35 MAJOR PHYLA GROUPS • VERTEBRATES= HAVE A BACKBONE - 3% OF ANIMALS 4. INVERTABRATES= HAVE NO BACKBONE - 97% OF ANIMALS
5. ENDOSKELETON= SKELETON INSIDE 6. EXOSKELETON= SKELETON OUTSIDE
7. VERTEBRATES= AN ORGANISM WITH A BACKBONE 8. INVERTEBRATE= AN ORGANISM WITHOUT A BACKBONE
TYPES OF VERTEBRATES: 1. ENDOTHERM= BODY TEMPERATURE REGULATED INSIDE AUTOMATICALLY -“WARM BLOODED” 2. ECTOTHERM= BODY TEMP. NOT REGULATED INSIDE -“COLD BLOODED”
TYPES OF SYMMETRY: 1. SYMMETRY= BALANCED ARRANGEMENT OF PARTS 2. RADIAL= CIRCULAR, SO MANY WAYS TO DIVIDE INTO LIKE PARTS - STARFISH, JELLIES, SEA URCHINS -NO FRONT / BACK -ALL LIVE IN WATER -SLOW MOVERS / CREEPERS -ARRANGED IN A CIRCLE AROUND A CENTER
3. BILATERAL= TWO SIDES ALIKE -ALMOST MIRROR IMAGES -RGT / LFT ALIKE -LARGER MORE COMPLEX ORGANISMS -QUICK / EFFICIENT MOVEMENT -SENSE ORGANS IN FRONT
BREATHING METHODS: • LUNGS= ORGANS TO REMOVE OXYGEN FROM THE AIR • GILLS= ORGANS TO REMOVE OXYGEN FROM THE WATER
MOVEMENT: • APPENDAGES= ATTACHEMENTS TO THE BODY THAT ALLOW IT TO SENSE ENVIRONMENT. -MOVE THROUGH: AIR, WATER, AND ON LAND 2. TENTACLES= ADAPTED FOOT -CEPHALOPODS= NAUTILUS, OCTOPUS, SQUID
3. TUBE FEET= A WAY TO MOVE AN ECHINODERM -ECHINODERM= STARFISH -WATER IN THE TUBE ALLOWS FOR SUCTION AND MOVEMENT
1. ALL ASEXUAL REPRODUCTION CREATES AN IDENTICLE OFFSPRING! 2. BUDDING= THE NEW ORGANISM FORMS ON THE SIDE OF THE ORIGINAL ASEXUAL REPRODUCTION:
3. FRAGMENTATION=WHEN THE ORIGINAL BREAKS INTO PIECES AND EACH NEW PIECE GROWS INTO AN INDIVIDUAL
SEXUAL REPRODUCTION: 1. INTERNAL FERTILIZATION= SPERM IS PLACED IN THE FEMALE TO COVER THE EGGS IN HER BODY. 2. EXTERNAL FERTILIZATION= EGGS ARE RELEASED OUTSIDE THE BODY. SPERM IS THEN RELEASED OVER THE EGGS
DEVELOPMENTAL STAGES: 1. METAMORPHOSIS= A CHANGE IN FORM FROM LARVAL STAGE TO ADULT A. INCOMPLETE= EGG, NYMPH, AND ADULT -NYMPH= STAGE WHERE THE YOUNG LOOK LIKE A SMALL VERSION OF THE ADULT -GRASSHOPPER, LICE, CRICKET
B. COMPLETE= EGG, LARVA, PUPA, ADULT - LARVA= IMMATURE FORM THAT LOOKS VERY DIFFERENT FROM THE ADULT FORM -PUPA= WHERE THE LARVA CHANGES INTO THE ADULT -BUTTERFLY, BEETLE, BEES
