cells in a multicellular organism adhere to one another, but cells in a colonial organism do not.
cells in a colonial organism communicate with one another but cells in a multicellular organism do not.
cells in a colonial organism adhere to one another, but cells in a multicellular organism do not.
cells in a multicellular organism communicate with one another but cells in a colonial organism do not.

Explanation:

In both colonial and multicellular organisms, cells adhere and communicate. However, in a multicellular organism, cells adhere to one another to form a more integrated and specialized structure, while in a colonial organism, the cells are more loosely - associated.

Answer:

Cells in a multicellular organism adhere to one another, but cells in a colonial organism do not. (The first option is correct as it reflects the fundamental difference in cell - adhesion between the two types of organisms)
