Defining characteristics of Platyhelminthes
-bilateral symmetry
-incomplete digestive system
-gastrovascular cavity
-excretory system made of "flame cells" and pores
-nerve ladder
-sexual and sexual reproduction
-regenerating powers
-hermaphrodite
-the beginning of cephalization with a brain and sense organs beginning to appear
-3 classes; turbellaria, trematoda, and cestoidea
-eyespots, auricles, pharynx, yolk gland, testes and ovaries, hook, suckers, scolex, proglottid etc.

Results:
6.
a) bilateral
b) acoelomates and triploblastic with bilateral symmetry
c) incomplete with flame cells and pores
d)"nerve ladder" nerve system
7.
a) meaning they have both female and male sex cells
b) a more organized nervous system that has a collection of nerves connecting the nerve cords, granting a ladder shape
c) an excretory cell that function like a kidney, removing waste
d) the ability to reproduce by regenerating tissue; commonly seen in flatworms
