Eukaryote formation:

Eukaryotic cells are possessed by all multicellular and some single celled organisms (protozoans). There is a vast difference between prokaryotic cells and eukaryotic cells. In particular, the latter perform functions inside compartmentalized structures called organelles. Therefore, the former are called simple cells. Given this comparison, the theory of evolution would dictate that the simple cells (prokaryotes) have evolved into the complex cells (eukaryotes). Indeed evolutionists have proposed that the eukaryotic cell evolved from a symbiosis or fusion of several distinct prokaryotes. This hypothesis is known as endosymbiosis. It is thought that specialized eukaryotic organelles such as the mitochondria, and choroplasts originated by internalizing aerobic bacteria like spirochaetes, and bluegreen algae respectively.
Like all of the theory of evolution, endosymbiosis is taught as though it is a fact, but there remains an inexplicable distinction between these two vastly different cell types. Eukaryotes have an extensive series of membrane-bound organelles including the endoplasmic reticulum, golgi apparatus, nuclear envelope. Eukaryotes also possess microtubular organelles such are cilia and centrioles, and their chromosomes are multiple instead of single and contain proteins as well as DNA.
"In tracking the emergence of the eukaryotic cell, one enters a kind of wonderland where scientific pursuit leads almost to fantasy. Cell and molecular biologists must construct cellular worlds in their own imaginations. ... Imagination, to some degree, is essential for grasping the key events in cellular history." -- B.D. Dyer and R.A. Obar, Tracing the History of Eukaryotic Cells, Columbia University Press 1994, pp. 2 & 3.
