Detailed explanation-1: -So the correct option is ‘prokaryotes evolved before eukaryotes’.
Detailed explanation-2: -Prokaryotic cells were some of the earliest life forms on earth. They first appear in the fossil record around 4 billion years ago. Prokaryotes were around for a long, long time before eukaryotic cells appeared around 1.8 billion years ago.
Detailed explanation-3: -According to the endosymbiotic theory, the first eukaryotic cells evolved from a symbiotic relationship between two or more prokaryotic cells. Smaller prokaryotic cells were engulfed by (or invaded) larger prokaryotic cells.
Detailed explanation-4: -Final answer: They have a well-organized nucleus and they have a nuclear membrane statements are true for eukaryotic cells.
Detailed explanation-5: -Prokaryotic cells do not have a well defined nucleus. Their genetic material is called a nucleoid. Membrane bound cell organelles are absent. They are surrounded by a cell wall.
