Biology stufff! Animals and classificiations. O:... And candy!

Hey. Okay, so I have finals tomorrow and I’m sure this question is going to be on it. “what characteristics define an animal?” I know they’re multi-cellular and lack cell walls and are motile or sessile. But what else?

Also.. To classify animals is it… Porifera, cnidarians, platyhelminthes, nemotada, mollusca, annelida, echinoderm, anthropods, chordata. Or am I totally wrong?

Pleaaase. Help. Thanks.:]

Answer #1

Candy? Where?

Animals are multicellular eukaryotic heterotrophs. They are capable of movement and sexual reproduction and they have diploid cells with no cell wall.
