Ctenophora
100
These are the only two types of body forms.
What are polyp and medusa?
100
These are the two different types of reproduction a Cnidaria can do.
What is sexual and asexual reproduction?
100
This class used to be part of then schphozoa, but got its own class because it is cuboidal.
What is a cubozoa?
100
A coiled filament with a poison tipped harpoon at the end.
What is a nematocyst?
100
This is the type of symmetry Ctenophora have.
What is biradial symmetry?
200
This body form has a bell shaped opening downward facing tentacles.
What is a medusa?
200
This is how sexual reproduction takes place in a Cnidaria.
What is a cycle?
200
This class does not contain medusa, only have sexual reproduction, and have eight tentacles.
What is a staurozoa?
200
The two types of symmetry cnidarians have.
What is radial and biradial symmetry?
200
These are the adhesive structures in Ctenophora.
What is a colloblast?
300
This body form is sessile, which means it does not move.
What is a polyp?
300
This is a larval stage in sexual reproduction.
What is planula?
300
This class has cnidocytes in both the gastrodermis and epidermis and the medusa is prominent.
What is scyphozoa?
300
This is a cilia that open the operculum, which is the cap of the cnidocyte.
What is a cnidocil?
300
These are ciliary bands used for locomotion.
What are comb rows?
400
This body type is dioecious, which means there are males and females.
What is a medusa?
400
These are the different parts of sexual repeated cycle.
What is fertilization, zygotes, blastula, planula, and polyp?
400
This class ha son medusa, has cnidocytes in the gastrodermis, and have their gastrovascular cavity decided into sections by internal mesenteries.
What is an anthozoa?
400
These secrete enzymes to digest the food.
What are gastrodermal gland cells?
400
An example of an animal in the phylum Ctenophora.
What is a comb jelly?
500
This body form is vase-shaped with upward facing tentacles.
What is a polyp?
500
This is how the sperm and eggs fertilize in sexual reproduction.
What is fertilizing in open water?
500
This class has nematocysts only in the epidermis and their mesoglea is acellular.
What is a hydrozoa?
500
This area is used for digestion, exchange of gases, waste, and gamete production.
What is the gastrovastcular cavity?
500
Both Cnidaria and Ctenophora have this cavity.
What is the gastrovascular cavity?
