Natasha2012 [34]

Answer:

<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common  function and form organs.</u>

Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
