Small marine worms, segmented, cuticle for protection, setae, or spine for locomotion

Gastrotrichs

Tiny marine, freshwater, and moist soil organisms, simple digestive system with mouth and anus, locomotion by cilia
2. Use Table A to classify the multicellular organisms and to complete Table B.

a Examine the images in the Multicellular Organisms Gallery at the end of this document.

b. For each organism, write the traits of the organism in the second column of Table B. Be sure that the organism number on the Image and the table match.

c. Identify the phylum to which each orgariism belongs. Write the name of the phylum in the third colurrin of Table B.

d. Write whether the orgariism is a plant, animal, or fungus in the fourth column of Table B.
