No symmetry
What makes up the skeleton of the sponge
Fibrous protein called spongin and hard spicules of calcium carbonate or silica
Sponges have an internal cavity called
Spongocoel
How do water and wastes leave the spongocoel
Large opening called osculum
Where is osculum located
At the top of the sponge
What is the type of feeding used by Porifera called
Filter feeding
Grantia
Domain: Eukarya
Kingdom: Animilia
Subkingdom: Parazoa
Phylum: Porifera

Hermaphroditic
Hermaphroditic
Produces male and female gametes
How can granite reproduce
Sexually and Asexually
How does granita reproduce sexually
Releases sperm which swims to the eggs within other sponges for fertilization. The resulting zygote grown into embryo within the parent sponge and released out of the spongoceal through the osculum
How can granite reproduce asexually
Fragmentation
Friends of Grantia
Spongilla
Phylum Cnidaria
Stinged cells: Jellyfish, corals and sea anemones
Cnidarians are
Diploblastic
What does diploblastic mean
It means that it has an outer layer (ectoderm) and an inner layer called endoderm
What is the endoderm and ectoderm held together by
Mesoglea
What is the body plan of Cnidarians called
Diploblastic coelomate
What kind of symmetry to cnidarians have
Radial
What ti cnidarians have
Tentacles
What are these tentacles covered by
Cnidoblasts cells
what do cnidoblasts cells contain
nematocyst
What are nematocysts used for
Microscopic, usually venomous harpoons used to immobilize and capture prey or for defence purposes
How do cnidarians eat
Tentacles push prey into the mouth/anus. the mouth and the anus is the opening of the gastrovascular cavity that has only one opening
