Three uniting characteristics of animals monophyletic group that is multicellular+ no cell
wall, heterotrophic, and move on their own power at some point in their life.
Sponges are animals that lack nerve cells and muscle cells
Two major innovations of the animal body plan tissues, and segmentation
why are tissues important tissues in animals were important because they lead to
differentiation of cells that made up specialized organs.
diploblast an animal that develops from two embryonic germ layers the ectoderm and
endoderm.
Triploblastic has three germ layers: the ectoderm, endoderm, and mesoderm.
what germ layer makes complex muscles for movement mesoderm
diploblast animals are the... cnidaria, and the Ctenophora
Animals with radial symmetry Cnidaria, and Echinodermata
Animals with bilateral symmetry are the same looking from one side to the other.
what are the two phyla that have a nerve net, and what sort of symmetry do they have?
Cnidarians and Ctenophores (diploblasts), they both have radial symmetry.
what sort of nervous system do those with bilateral symmetry have? Central nervous system
, sessile Nonmoving
are sponges always sessile Sponges are motile as larvae and sessile as adults.
name three characteristics of sponges No tissues, organs, or nerve cells; no definite
symmetry, cells can reaggregate.
how do sponges eat Sponges are suspension feeders, capturing food particles suspended in
the water that pass through their body
what special cell do sponges use for feeding sponges use choanocytes for feeding.
what are the organisms in the cnidaria phylum Jellyfish, corals, anemones, and hydroids.
what is the two body types of cnidaria the polyp, and the medusa
polyp Cnidarian organisms that are cylindrical, and sessile
medusa Cnidarian organism that is umbrella shaped, and free living.
metagenesis Cnidarian life cycle goes through sexual and asexual stages.
what body shape of the cnidarian is asexual in the life cycle polyp
