16. MULTICELLULARITY 4 COLONIAL - CELLS PERMANENTLY ASSOCIATED BUT DO NOT COMMUNICATE 4 AGGREGATIONS - TEMPORARY COLLECTION OF CELLS THAT COME TOGETHER FOR A PERIOD OF TIME AND SEPARATE

17. TRUE MULTICELLULARITY 4 COMPOSED OF MANY CELLS THAT ARE PERMANENTLY ASSOCIATED WITH ONE ANOTHER 4 SHOWS DIFFERENTIATION BY DEVELOPING SPECIALIZED FORMS AND FUNCTIONS
