TAXONIMIC HIERACHY

 Kingdom, Phylum, Class, Order, Family, Genus, Species

FEWEST MEMBERS---------------------------->MOST MEMBERS

MORE BIODIVERSITY-------------------------->LESS BIODIVERSITY

We can see if animals are closely related by DNA+Protein analysis/sequencing :D

1 of 18

KINGDOMS - ANIMALIA

  • Multi-cellular (made up of more than one celll so it can specialise cells which is vr helpful and u look cooler)
  • Nervous Co-ordination
  • Hetertrophic (we can not make our own food so we need to get food from tesco or somewhere)
  • Eukaryotic (that cell which has a nucleus and 70s ribosomes and stuff from BY1)
  • No cell wall (dat would be stupid)

 

2 of 18

KINGDOMS - PLANTAE

  • Autotrophiccc dudes (make there own food via photosynthesis, they so trendy they manufacture their own organic molecules from simple inorganic molecules - JUST LIKE MAGIC. can u do that? huh huh huh?)
  • Cell walls made of CELLULOSE
  • Multi-cellular (this plantae keeps getting cooler and cooler y aren't we all plantae?)
  • Eukaryotic

 

3 of 18

KINGDOM - PROKARYOTA

  • Prokaryotic (wow shock horror)
  • No membrane bound organelles (as is key with prokaryotic organisms... so implied that by it being prokaryotic in the first place but there we go it gonna have it's own bullet point now)
  • Cell wall present (NOT cellulose dis timeee)
  • Uni-cellular (aww dat sad - alll by ittsellf)
  • Microscopic

 

4 of 18

KINGDOM - FUNGI

  • Eukaryotic (anotherrr one)
  • Reproduce by spores (not the computer gameee)
  • Heterotrophic (goes out to get it's food from mcdonalds :D)
  • Cell walls made of CHITIN (chai-tin)

 

 

 

5 of 18

KINGDOM - PROTOCTISTA

  • Eukaryotic
  • Generally uni-cellular (because this kingdom is kinda a mix of all of those left out from the other groups :( aww poor babies)
  • No tissues

BIODIVERISTY HAS BEEN GENERATED THROUGH NATURAL SELECTION AND ADAPTED OVER MILLIONS MILLIONS MILLIONS MILLIONS OF YEARS.

BINOMIAL SYSTEM

OH YEAH ALSO EVERY LIVING THING IS NAMED ACCORDING TO THE BINOMIAL SYSTEM WHICH IS THE SCIENTIFIC NAME FOR THINGS AND CONTAINS THEIR GENUS AND SPECIES TO MAKE UP THEIR NAME.

HOMO (GENUS) + SAPIEN (SPECIES) = HOMO SAPIEN

THIS IS A GOOD THING BECAUSE THESE NAMES ARE KNOWN UNIVERSALLY SO ANY LANGAUGE CAN UNDERSTAND THEM

PHYLUMS

TWO TYPES OF PHYLUM - MAJOR AND MINOR

MAJOR PHYLUM IN ANIMALIA KINGDOM INCLUDE:

-Chordates

-Anthropoda

-Annelida

THESE ARE THE ONES WE NEED TO KNOW ABOUT!!! :D

9 of 18

CHORDATES

INCLUDES: MAMMALS, BIRDS, REPTILES, AMPHIBIANS + FISH

  • Internal skeleton including a cranium
  • Post-anal tail (area for locomotion is beyond the ****; on humans our legs are beyond/post our ****)
  • Closed circulatory system
10 of 18

MAMMALS

  • HAIRYYY
  • GIVE BIRTH TO LIVE YOUNG (USUALLY)
  • INTERNAL FERTILISATION
  • INTERNAL DEVELOPMENT OF OFFSPRING
  • FEED YOUNG ON MILK; HAVE MAMMARY GLANDS
  • SWEAT GLANDS
  • ENDOTHERMIC (HEAT COMES FROM INSIDE)
11 of 18

BIRDS

  • WINGS
  • FEATHERS COVERING SKIN, FEET COVERED IN SCALES
  • LAY HARD-SHELLED EGGS ON LAND
  • INTERNAL FERTILISATION
  • EXTERNAL DEVELOPMENT
  • AIR SACS
  • ENDOTHERMIC
12 of 18

REPTILES

  • SCALY SKIN (WATERPROOF)
  • LAY SOFT-SHELL EGGS ON LAND (SOFT-SHELL STOPS IT DRYING OUT)
  • LUNGS
  • INTERNAL FERTILISATION BUT EXTERNAL DEVELOPMENT
13 of 18

AMPHIBIANS

  • LAYS EGGS IN WATER
  • SMOOTH SKIN
  • LUNGS WHEN ADULT (GILLS WHEN YOUNG)
  • EXTERNAL FERTILISATION
  • EXTERNAL DEVELOPMENT; EGGS
14 of 18

FISH

  • SCALY SKIN (MOST DO - NOT EELS THOUGH OR SHARKS)
  • GILLS (INSIDE THE BODY)
  • LOCOMOTION USING FINS
  • EXTERNAL FERTILISATION
  • EXTERNAL DEVELOPMENT ; EGGS
15 of 18

ANTHROPODA

INCLUDES: INSECTS

  • Jointed legs, multiple legs (minimum 3 paris)
  • Exoskeleton (made of chitin)
  • segmented body, fluid filled body cavity
  • open circulatory system

 

16 of 18

INSECTS

  • THREE BODY SEGMENTS (HEAD, THORAX, ABDOMEN)
  • THREE PAIRS OF LEGS
  • TWO PAIRS OF WINGS (IN SEXUALLY MATURE ADULTS AND FLEAS DON'T HAVE THEM ANYMORE AS THEY DON'T NEED THEM)
  • HEART ALONG THEIR BACKS (EW)
17 of 18

ANNELIDA

  • segmented body
  • moist skin for gas exchange
  • closed circulation (blood contained in veins and arteries)

Okay, I know this looks like it was done by someone as a joke on Tumblr, but it's actually a really helpful resource. I can probably remember these things 10x because of the commentary.

Fun is a good learning method.
