Lab 10: Kingdom Animalia Introduction Animals all share some characteristics:
1) Multicellular
2) Heterotrophic
3) Their cells have no cell wall
4) At some time in their life they are motile.
There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to.
Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla.
a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples.
b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…
