CHARACTERISTICS OF COMPLEX ANIMALS:
1)
Highly specialized
cells and body tissues
2)
Bilateral body
symmetry
3)
Front end or head
with sense organs
(cephalization)
4)
A body cavity
SPECIMENS ACTIVITY:
 For
each of the numbered specimens, tell me:
 A)
What is its name(s)?
 B) Type of body symmetry? (none, radial, bilateral)
 C) Is there cephalization?
 D) Complex or simple animal?
 E) Which phylum does it belong to?
 F) Can you identify the class? Order? Etc

INTRODUCTION TO KINGDOM ANIMALIA:
 Most
diverse kingdom in terms of physical appearance
 Each
phylum has its own body plan, meaning:
unique anatomy (organization and type of tissues)
 Over
95% of all animals are invertebrates
Only about 5% are vertebrates
 All
animals have the following characteristics:
a) heterotrophic
b) multicellular
c) eukaryotic cells with no cell wall
ALL ANIMALS CARRY OUT THE FOLLOWING PROCESSES:
 a)
Feeding
 b) Respiration
 c) Circulation
 d) Excretion
 e) Response (to stimuli)
 f) Movement
 g) Reproduction
 What
are four characteristics that “complex
animals” have in common?
“Thinking
visually”

EARLY DEVELOPMENT IN ANIMALS:
Zygote
= egg fertilized
by sperm
Blastula
= hollow ball
of cells (formed by
dividing zygote)
Blastopore
= opening
(inner tube) in the
blastula
EARLY DEVELOPMENT IN ANIMALS:
 Protostome
= an animal whose
blastopore becomes their mouth
(‘proto’  ‘first’, and ‘stoma’  ‘mouth’)
 Deuterostome
= an animal whose
blastopore becomes their anus
(‘deutero’  ‘second’, ‘stoma’  ‘mouth’)
 *All
vertebrates are deuterostomes
 *Answer
question #4 on page 663
EARLY DEVELOPMENT IN ANIMALS:
 Endoderm
= ‘inner skin’
Forms digestive tract + respiratory
system
 Mesoderm
= ‘middle skin’
Forms muscles, circulatory,
reproductive, excretory systems
 Ectoderm
= ‘outer skin’
Forms sense organs, nerves, outer
layer of skin
PRESENTATIONS: GENERAL COMMENTS
Speak
clearly (volume and speed)
Show interest
Make eye contact
Avoid reading (power point, not
power paragraph)
Both presenters should speak
Don’t run away and sit down while
people are asking questions
Know
your material (meanings and
pronunciations)
If you don’t understand it, don’t
include it in the presentation-or
(even better) find out what it means
Proofread for errors (spelling,
missing words)
Include sources of information
Include information asked for in
rubric given by the teacher
FOR THE TEST:
Notes
copied from power point
Handout assignment for section
26-1
Chart of animal groups’
identifying characteristics
Crossword review puzzle will help
