Cladogram worksheet

Sorry for the bad handwriting.  This is why I normally type assignments up...  Just in case, I will retype the answers below...

1. Multicellularity.

2. Scyphozoa and cubozoa.  They are on their own branch.

3. No, only scleractinians.  Because calcium carbonate production appears at the scleractinia branch.

4. Rhopalium.

5. Anthozoa.  The polyp body form as an adult is what separates class anthozoa, so all the orders within anthozoa have it.

6. Tissues. Nematocysts.
