In string theory/M theory, there are two types of strings, open and closed strings. What kind of strings are fermions(electrons, quarks) made out of? Closed or open strings?

From the book The Trouble with Physics by Lee Smolin, the ends of open strings can represent charged particles and closed ones can represent the graviton. See page 106.
