I suppose that the majority of the cheesecake does not consist of eukaryotic cells, but there are definitely plenty of them in there. I’ve never looked at milk under a microscope but I would expect it to contain cells from the cow. The lemon zest contains lemon cells. The graham cracker crust contains wheat. Dead cells would not be much simpler than living cells.
What? It’s products of eukaryotic life. Usually the eukaryotes are dead. Though plenty of microorganisms immediately start colonizing.
Unless you mean the other kind of cheesecake.
