Objective 5 0 and 5 3

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

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


Objective 5 0 and 5 3

5. ENDOSKELETON= SKELETON INSIDE

6. EXOSKELETON= SKELETON OUTSIDE


Objective 5 0 and 5 3

7. VERTEBRATES= AN ORGANISM WITH A BACKBONE

8. INVERTEBRATE= AN ORGANISM WITHOUT A BACKBONE


Types of vertebrates

TYPES OF VERTEBRATES:

1. ENDOTHERM= BODY TEMPERATURE REGULATED INSIDE AUTOMATICALLY

-“WARM BLOODED”

2. ECTOTHERM= BODY TEMP. NOT REGULATED INSIDE

-“COLD BLOODED”


Types of symmetry

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


Objective 5 0 and 5 3

3. BILATERAL= TWO SIDES ALIKE

-ALMOST MIRROR IMAGES

-RGT / LFT ALIKE

-LARGER MORE COMPLEX ORGANISMS

-QUICK / EFFICIENT MOVEMENT

-SENSE ORGANS IN FRONT


Objective 5 0 and 5 3

4. ASYMMETRY= NO BALANCED DESIGN


Breathing methods

BREATHING METHODS:

  • LUNGS= ORGANS TO REMOVE OXYGEN FROM THE AIR

  • GILLS= ORGANS TO REMOVE OXYGEN FROM THE WATER


Movement

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


Objective 5 0 and 5 3

3. TUBE FEET= A WAY TO MOVE AN ECHINODERM

-ECHINODERM= STARFISH

-WATER IN THE TUBE ALLOWS FOR SUCTION AND MOVEMENT


Asexual reproduction

1. ALL ASEXUAL REPRODUCTION CREATES AN IDENTICLE OFFSPRING!

2. BUDDING= THE NEW ORGANISM FORMS ON THE SIDE OF THE ORIGINAL

ASEXUAL REPRODUCTION:


Objective 5 0 and 5 3

3. FRAGMENTATION=WHEN THE ORIGINAL BREAKS INTO PIECES AND EACH NEW PIECE GROWS INTO AN INDIVIDUAL


Sexual reproduction

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

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


Objective 5 0 and 5 3

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
