Flashcards in Kingdom Animalia Phylum 1-4 and 6 Deck (126)
What is Kingdom Animalia also known as?
What are the characteristics of Kingdom Animalia?
Heterotrophic, multicellular, no cell wall, most have locomotion.
What is the first phylum of Kingdom Animalia?
What is phylum Porifera made of?
How many species are in phylum Porifera?
Is Porifera a relatively big or small group?
Where do Porifera live?
Mostly live in the ocean.
What kind of symmetry do Porifera have?
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?
What is the average number of species in Cnidaria?
Is Cnidaria a relatively small or big species?
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
