Warm Up Question:
Take Cornell Notes For All The
Following Info:
Characteristics of Animal
Kingdom
• Multicellular-Having or consisting of many cells or more than
one cell to perform all vital functions.
• Eukaryotic-possessing a membrane-bound nucleus
• Heterotrophic-not capable of producing their own food, have
to feed on organic matter for energy
• Cells Lack a Cell Wall-animals and most protists do not
have cell walls
Animals Carry Out The
Following Functions:
•

Reproduction
95% off all animals are invertebrates (no back
bone, example-insects)
Single Celled Ancestor
• First came the unicellular organism also
known as a single celled organism is an
organism that consists of only one cell.
• (Prokaryotes, most protists, and some kinds
of fungi are unicellular.)
Multicellular
• Then came the multicellular organisms are
organisms that consist of more than one
cell.
• Most life is multicellular, as are all animals
(except for specialized organisms such as
Myxozoa) and land plants.
#1 Porifera: First of the Nine
Phyla
• Phylum NamePorifera
• Common NameSponges
• All the same cells.
Then came…
• Differentiated Cells
• Cells for different parts of the body, such as
tissue cells to create organs.
#2 Cnidaria: Second of the Nine
Phylum
• Pronounced-nidaria, the c
is silent
• Have radial symmetryThese organisms resemble
a pie where several cutting
planes produce roughly
identical pieces.
• Examples-Jellyfish, sea
anemone
Then came…
• Next on the
Cladogram time line
is:
• Bilateral Symmetrymeaning that it could
be divided into
matching halves by
drawing a line down
the center.
#3 Platyhelminthes:Third of the
Nine Phylum
• Example is a
Flatworm (common
name)-soft-bodied
invertebrate animals
• Usually live inside
other organisms
#4 Nematode: Fourth of the Nine
Phylum
• Common name is Round
worms-they are more
advanced than flatworms
but less advanced than
earthworms. They have
thin round bodies.
• Many of them are
harmful, as they are
parasites.
• Pseudocoelom - internal
body cavity of some
primitive invertebrates,
lacking a mesodermal
layer
Then came…
• Next on the Cladogram time line is:
• Coelom-a confined body cavity surrounding
the internal organs
#5 Mollusca: Fifth of the Nine
Phylum
• Examples-Shellfish,
squids, snails
• Mollusks have a soft
body (their name is
derived from the Latin
word mollus, meaning
"soft”)
#6 Annelid:Sixth of the Nine
Phylum
• Annelids are a large
phylum of segmented
worms
• Example- earthworms
and leeches.
#7 Arthropod:Seventh of the
Nine Phylum
• Arthropod-is an
invertebrate animal
having an exoskeleton
(external skeleton), a
segmented body, and
jointed appendages
• Examples-Insects,
crabs, lobsters
#8 Echinoderm: Eighth of the
Nine Phylum
• Echinoderms are
characterized by radial
symmetry, several
arms
• Examples-Sea star or
starfish, sea urchins
#9 Chordate:Ninth of the Nine
Phylum
• Chordate-are animals
which are vertebrates
(backbones)
• Animal groups in the
chordate phylum
include fish,
amphibians, reptiles,
birds and mammals.
