A protist has a nucleus inside of it to make it a Eukaryote, if it had no nucleus it would be consider a Prokaryote
        
             
        
        
        
There are two important regions of a lipid that provide the structure of the lipid bilayer. Each lipid molecule contains a hydrophilic region, also called a polar head region, and a hydrophobic, or nonpolar tail region

Explanation:
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
so its basically passive
