Characteristic in Kingdom Animalia Flashcards
What are some characteristic in kingdom Animalia
-NO CELL WALL
-Movement/mobile
-Eukaryotic
-Multicellular
Symmetry in animals and what are they
Bilateral symmetry- Only ONE set of PLANE that has equal half
Radial symmetry - Can be divided on ANY PLANE
Sponge has NO symmetry
Germ layer ( _ germ layer)
LAYERS OF TISSUE FORMED DURING EARLY DEVELOPMENT
Endoderm - The lining of gut ENDO = IN
Ectoderm -The outer skin and nervous system ECTO = OUT
Mesoderm - Located in organs, brain, blood vessels
Where can these germ layer be found in
Sponges, Cnidarians, jellies, anemonies
Heat regulation Poikilotherm
ECTOTHERMS (poikilotherm)
-UNABLE to regulate body temp
Ex: Sharks, camels, tuna, insects snakes, lizards
Heat regulation Homotherm
ENDOTHERM (homeotherm)
-CAN REGULATE body temp
Ex: ALL mammals besides naked mole rats
True or False
Sessile means the organism can move their entire life
FALSE
Sessile means STATIONARY as ADULTS since all baby animals can move
EX: corals + enemies
Motile
Animal is MOBILE their ENTIRE LIFE
What is segmentation
Body is/or not divided into repetitive sections
Ex: Ants have head, thorax and abdomen which are all parts of the body divided
True or False: BODY FORM
Polyp means its attached to the body (sessile)
Medusa means free floating body (motile)
Give an example of polyp and medusa
TRUE
Polyp:
Medusa: jelly fish
Where is the support in a endoskeleton
Give examples
ENDO = INSIDE
Support is on the INSIDE
Humans, birds, dogs all have support on INSIDE
Where is the support in a exoskeleton
Give examples
EXO = OUtside
Suport is the EXTERNAL OUTER COVERING NOT SKELETON/BONES
Crabs, armadillos, shrimps all have EXTERNAL OUTER COVERINGS
What are the four gas exchange surface
- Lungs
2.INTERNAL gills
3.EXTERNAL gills - Trachaea
What does Chordata mean?
Chordata means organisms with a BACKBONE/VERTABRE
Usually all animals have chordata as it is the Class (hierarchy classification)
