FIRST TAKE NOTES
Column A: Write questions
Column B: Take your notes
appearance of each phylum = evolution of a successful body plan
Major trends:
Specialized cells, tissues, and organs
sponges & cnidarians = little specialization
flatworms = organs
mollusks and arthropods = organ systems
Body symmetry
sponges have no symmetry. All other invertebrates have symmetry
cnidarians & echinoderms have radial symmetry
worms mollusks and arthropods ahve bilateral
Cephalization
invertebrates with cephalization can respond in more sophisticated
ways
most worms and arthropods have ganglia
more complex animals have brains
Segmentation
usually, bilateral symmetrical organisms will have segmentation
Different segments will have specialized functions
allows animals to increase body size with a minimum of genetic
material

THEN WRITE QUESTIONS
Column A: Write questions
Column B: Take your notes
appearance of each phylum = evolution of a successful body plan
Major trends:
How are very simple
invertebrates different from
more advanced
invertebrates?
Specialized cells, tissues, and organs
sponges & cnidarians = little specialization
flatworms = organs
mollusks and arthropods = organ systems
How can symmetry be used
to classify these organisms?
Body symmetry
sponges have no symmetry. All other invertebrates have symmetry
cnidarians & echinoderms have radial symmetry
worms mollusks and arthropods ahve bilateral
What is the advantage of
cephalization?
How does segmentation give
an advantage to organisms?
Cephalization
invertebrates with cephalization can respond in more sophisticated
ways
most worms and arthropods have ganglia
more complex animals have brains
Segmentation
usually, bilateral symmetrical organisms will have segmentation
Different segments will have specialized functions
