Sindrei [870]

Answer:

2.They exhibit cell specialization.

Explanation:

A protist is an eukaryotic organism that can either be unicellular or multicellular. In the multicellular protist i.e. many cells, different types of cells are needed to bring about the organism's life processes. The different types of cells perform a specific different function in the organism.

The way that an organism makes it cells specialized to perform different functions is called Cell Specialization or differentiation. All multicellular organism, including a multicellular protist, contain many cells that have been specialized to perform different functions. Hence, the many cells of a multicellular protist will exhibit specialization in order to perform varying functions in the organism.
