one +1 (347) 23221 332 44 minutes ago 2.Complete the following table Comparing the different animal aroups: Sponge Roundworm Crayfish Symmetry (yes or no; If yes what kind) Tissue organization (yes or no; if yes how many layers) Type of body Complete the following table, which uses a representative aniimal from certain phyla: 3. Sponge Hydra Flatworms Roundworms Multicellularity No true tissues True tissues Radial symmetry two germ layers (only Bilateral symmetry; three germ layers Acoelomates Body cavity Pseudocoelomates

Explanation / Answer

Sponge

Hydra

Roundworm

Crayfish

Symmetry (yes or no), if yes what kind

No

(Sponges are multicellular organisms. Their bodies are full of pores through which they allow water to circulate through them. Spores have no body symmetry)

Yes

(Hydra has a tubular or radial body symmetry.

Yes

(Roundworm has distinct head with bilaterally symmetrical body)

Yes

(Crayfish has bilateral body symmetry)

Tissue organization (yes or no), if yes how many layers

No

(Sponges lack true tissues and organs)

Yes

(Hydra has two tissue layers an outer layer and an inner layer)

Yes

(Roundworms organs are derived from three tissue layers)

Yes

(Crayfish has three layer tissue organization)

Type of body cavity

Sponges have no real body cavity besides a central body cavity (gut) where they deposit their nutrients

Hydra has a Coelenteron body cavity.

Roundworms have pseudocoel body cavity other than gut

Crayfish has true coelom body cavity
