Some of the organisms studied in lab 9 are pictured below.  You areresponsible for all organisms studied, not just hte ones below.
This review is intended to help you:

• Be able to identify each organism by sight
• Place each organism in the correct kingdom and phylum, and in some cases class or subphylum
• Know the major characteristics of each organism, including unique ones

• body plan - radial, pentameric or bilateral symmetry
• # of embryonic tissue layers - diploblast or triploblast
• presence of body cavity - acoelomate, pseudocoelomate or coelomate
• developmental pattern - protostome or deuterostome
• properties of the digestive tract and circulatory systems
• any distinguishing traits of the organism (e.g.  tentacles of jellyfish)

After you have answered the above for each picture, scroll down to the bottom of the page for the answers.
Note that  the pictures are not to scale with each other.

Answers
All of these are in the kingdom Animalia - eukaryotic, heterotrophic, no cell wall, most have extracellular digestion

1.  butterfly - phylum Arthropoda, subphylum Uniramia, Class Insecta
 bilateral symmetry, triploblastic, coelomate, protostome
 one-way digestive tract with some specialization
 open circulatory system
other features: chitinous exoskeleton, segmented, flight

2. coral - phylum Cnidaria
radial symmetry, diploblastic, body cavity and developmental pattern not applicable
two-way digestive tract or harbors photosynthetic organisms
no circulatory system
other features: secretes carbon-based exoskeleton, lives communally
