The three main modes of movement in unicellular eukaryotes include cilia, flagella, and these
What are pseudopodia?
100
These are the feeding cells of sponges, also called "collar cells"
What are choanocytes?
100
Watch out! The tentacles of sea jellies are studded with stinging weapons called this
What are nematocysts?
100
Plebes might call ctenophores this.
What are comb jellies?
100
The common man may call platyhelminthes this
What are flat worms?
200
All unicellular eukaryotes contain these organelles, which were originally free-living bacteria
What are mitochondria?
200
Although multicellular, sponges lack this type of organization
What are tissues?
200
Sea anemones are members of this Cnidarian class.
What is Anthozoa?
200
While not the only animals that can do this, ctenophores are remarkable in that most of them do this, so that they may be seen even on the darkest nights 
What is bioluminescence?
200
The body cavity of platyhelminthes is not lined with endoderm, but is instead nestled within the mesoderm. This term describes that.
What is acoelomate?
300
Some unicellular eukaryotes contain these organelles, which were originally free-living bacteria that could photosynthesize
What are chloroplasts?
300
Calcarous or siliceous crystalline structures, as seen here, are found embedded in sponge walls, and are called this 
What are spicules?
300
These cnidarians are considered to be the "true jellies", due to the presence of the vellum
What is Class Scyphozoa?
300
Unlike cnidarians, ctenophora have an anus, which means that their digestive system can be described as this
What is complete?
300
Platyhelminthes possess ectoderm, mesoderm, and endoderm, which means they are this
What is triploblastic?
400
This disease is caused by a plasmodium that is transmitted from cats, via feces, to humans
What is Toxoplasmosis?
400
The three types of sponge forms include asconoid, syconoid, and this
What is leuconoid?
400
Cnidarians can often exist in two main forms: the medusa and this
What is the polyp?
400
Ctenophora move through water by beating rows of these
What are cilia?
400
This class includes the liver flukes.
What is Trematoda?
500
All unicellular eukaryotes contain this important cellular structure, which contains and protects the DNA
What is the nucleus?
500
Sponges pull water through ostia with the flow generated by this collar cell structure
What is the flagellum?
500
Cnidarians do not have a central nervous system, but they do have this, a system that we also have in our guts
What is a nerve net?
500
The body symmetry of ctenophores only exists on two planes because tentacles are paired. This type of symmetry is called this
What is biradial symmetry?
500
This class includes our adorable friends, the planaria, as seen here: 
What is Turbellaria?
