1. Function Biology II
Department of Agriculture andAgribusiness Management

2. Introduction to KingdomAnimalia
Eukaryotic
Multicellular
No cell wall, no chloroplasts
Motile
Heterotrophs
Sense Organs

3. Introduction to KingdomAnimalia
HERBIVORES- eat vegetation such
as plants

4. Introduction to KingdomAnimalia
CARNIVORES- eat other animals

5. Introduction to KingdomAnimalia
OMNIVORES- feed on both
vegetation & other animals

6. Introduction to KingdomAnimalia
Cell Specialization
Cephalization
Early Development
Body Symmetry
Body Cavity Formation

7. Specialized Cells
Tissues
Organs
Organ Systems

8. Introduction to KingdomAnimalia
Cells FormTissues
EPITHELIAL (Skin, Lining Of Cavities)
CONNECTIVE (Bone, Blood)
MUSCULAR (Heart, Biceps)
NERVOUS (Brain, Nerves)

9. Introduction to KingdomAnimalia
Concentration of sense organs
and nerve cells at front end of
body

10. Introduction to KingdomAnimalia
Fertilization forms A zygote
BLASTULA (hollow ball of cells)
GASTRULA (stage when layers
that produce adult tissues form)
GERM LAYER FORMATION

11. Introduction to KingdomAnimalia
Animal’s body plans are adapted
for how they get their food
They may be motile (move) or
sessile (don’t move)

12. Introduction to KingdomAnimalia
Asymmetrical-no symmetry (ex, sponge)

13. Introduction to KingdomAnimalia
Bilateral- body plan in which single line can
divide body into 2 equal parts

14. Introduction to KingdomAnimalia
Radial-body plan in which body parts repeat
around center of body

15. Introduction to KingdomAnimalia
Dorsal- top or back
Ventral- bottom
Anterior- head end that goes first
Posterior- tail end that follows
Lateral- along the side (lengthwise)

16. Introduction to KingdomAnimalia
Dorsal
Anterior
Posterior
Ventral

17. Introduction to KingdomAnimalia
ACOELOMATE- no body cavity b/w digestive
tract and outer body wall
ex. Platyhelminthes (flatworms)

18. Introduction to KingdomAnimalia
PSEUDOCOELOMATE- slight body cavity
between the mesoderm and endoderm
Ex. Nematoda (roundworms)

19. Introduction to KingdomAnimalia
COELOMATE- body cavity forms and cushions
organs, allows for growth of organs.
Ex. Annelids (earthworm)

20. Introduction to KingdomAnimalia
INVERTEBRATES
95% of animal species
No backbone
VERTEBRATES
5% of animal species
Contains backbone

REPRODUCTION

22.  Porifera—sponges
 Cnidaria—jellyfish, sea anemones, coral
 Platyhelminthes—flatworms
 Nematoda—roundworms
 Annelida—earthworms
 Mollusca—shelled animals
 Arthropoda—insects, spiders
 Echinodermata—spiny-skinned
 Chordata—vertebrates (and others)

23.  Asymmetrical
 Pores—filter feeders
 Not motile (sessile)
 Provide habitat for
other animals
 Eaten by starfish and
some fish
 Most primitive animal

24.  Digestive cavity called a
coelenteron
 Radial symmetry
 Predators-feed on
crustaceans
 Corals provide important
habitat for fish
 Coral used for decoration
and threatened by
pollution
 All have stinging cells

25.  Bilateral symmetry
 Cephalization- head and
brain
 Acoelomate- no body
cavity
 Incomplete digestive
system (one opening)
 Some are parasites in
digestive tract
 In early 1900’s models ate
them to be thin—YUK!

26.  Also called nematodes
 Complete digestive
system-separate mouth
and anus (2 openings)
 Pseudocoelomate
 Decomposers, predators
(bacteria, inverts)
 Eaten by insects, mice
 Beneficial to garden by
eating insects

27.  i.e. earthworms, leeches
 True coelom
 Sensitive to vibrations on
ground-rain
 Prey for robins, shrews,
jays, snakes
 Leeches have cornified
knobs to break skin,
anticoagulant and
anesthetic

28.  i.e. snails, slugs, clams,
mussels, scallops,
oysters, octopus and
squid
 Variety in form
 Giant squid = sea
serpent
 Introduction of garden
snails

29.  i.e. insects, spiders and
scorpions, shellfish
(crustaceans), centipedes
(1 pr legs per segment),
millipedes (2 pr)
 Exoskeleton
 Metamorphosis
 Pheromones
 Molting

30.  i.e. sea stars = starfish,
sea urchins
 Water vascular system
 Tube feet
 Important predators

31.  i.e. fish, sharks,
amphibians, reptiles,
birds, mammals
 Notochord, nerve cord,
gill slits, tail
