Kingdom Animalia Phylum 1-4 and 6 Flashcards
What is Kingdom Animalia also known as?
Metazoa
What are the characteristics of Kingdom Animalia?
Heterotrophic, multicellular, no cell wall, most have locomotion.
What is the first phylum of Kingdom Animalia?
Porifera.
What is phylum Porifera made of?
Sponges.
How many species are in phylum Porifera?
5,000 species.
Is Porifera a relatively big or small group?
Small.
Where do Porifera live?
Mostly live in the ocean.
What kind of symmetry do Porifera have?
No symmetry.
Do Porifera move?
No, they are sessile.
What does sessile mean?
To be permanently attached to a surface.
What does Porifera mean?
It means having pores.
How many layers of cells does a sponge have?
It has two layers of cells.
What are the two layers of cells in Porifera?
Ectoderm and the Endoderm.
What is the Ectoderm?
The outer cell layer.
What is the Endoderm?
The inner cell layer.
How do Porifera feed?
By filter feeding.
Describe filter feeding.
The water is brought in thru the pores and the oxygen and food are filtered in. The water leaves thru the osculum with waste and carbon dioxide (CO2).
What are the three types of sponge shapes?
I, T, Y.
What are spicules?
Mineral deposits made of silica.
Where do the spicules come out of?
They stick out thru the endoderm.
What is the function of the spicule?
Their job is to give the sponge its shape, structure, and form, like the skeletal structure.
What are the life stages of a sponge?
The sperm fertilizes the egg, which is a Zygote. This then becomes a larva and then an adult sponge.
Are larvae free swimming?
Free- swimming larvae.
What porifera do before they are adults?
Before they are adults they can move, but once they become a sponge they become sessile.
What is the second phylum of Kingdom Animalia?
Cnidaria.
What is the average number of species in Cnidaria?
10,000 species.
Is Cnidaria a relatively small or big species?
Average.
What are some examples of Cnidaria?
Hydra, Jellyfish, Mano War, sea anemone, and Coral.
Where do Cnidaria live?
Most live in the ocean, but some live in fresh water
What is the structure of a jellyfish?
It has an Ectoderm,, and Mesoglea, Endoderm
What is the middle of a jellyfish like?
It is hollow.
What is the gastrovascular cavity?
Where food is going to be digested.
What is the only opening of the jellyfish?
The mouth, which is also the anus.
What is the function of the jellyfish mouth?
The mouth takes in food and let’s waste go.
What surrounds the jellyfish mouth?
Tentacles.
What are cnidoblasts?
The stinging blasts that shoot out from tentacles.
How do hydra eat?
- They stings the prey.
- The fish is pushed inside their mouth and the gastrovascular cavity.
- The food is digested.
- The waste is pushed out by the tentacles through the mouth.
What type of symmetry do Cnidaria have?
Radial Symmetry.
What are the two kinds of symmetry?
Radial symmetry and Bilateral symmetry.
What is radial symmetry?
- It is the midpoint and body parts surround it.
- There are an infinite amount of ways to cut it.
- The terms the front of animals and back of animals mean nothing.
What is bilateral symmetry?
- Half the body is to the right or left.
2. You can only cut down the center and separate left from the right.
What does asymmetrical mean?
Lacking symmetry.
What are the two forms of Cnidarians?
Polyp and Medusa.
What is a Polyp?
Hydra and Coral are polyps: They are sessile and the tentacles and the mouth are pointing up and are at the top.
What is a Medusa?
The mouth and the tentacles are pointing toward the bottom of the animal and it can swim.
How do polyps make coral reefs?
They make a skeleton of calcium carbonate with little holes in it. The polyps lives inside the little holes.
What would happen if the polyps die?
The reef would die because there would be no polyps to build the coral reef.
What is the largest coral reef in the world?
The Great Barrier Reef in Australia.
What would happen if the barrier reef died?
If the reef dies that the major cities of Australia would be underwater in a matter of fifty years.
What is the third phylum of Kingdom Animalia?
Flatworms, or Platyhelminthes.
