cassette (minus one cog)
extra front chainring (and the spider)
derailleurs
shifters
That adds up to a kilogram, unless going for really high end stuff, doesn't it?
Oh, I forgot - SS usually has shorter chain as well, so in spite of it being a bit wider (heavier) per link, it ends up being the same weight, if not lighter than a multi speed one.

First I don't care about the weight. I am just responding to those who claim lighter. Second it never is the same frame, is it? Or the same level of crank. Stuff speced on SSs is simply very old fashioned and very heavy. As I said, you would have to really go custom to get close to a stock bike with say aluminum frame and Tiagra despite the many fewer parts. Once again, I'm not saying it matters. Just setting the record straight.
