Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. This explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. These prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast.
The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container.
Explanation:
TRUE!!!! Idk if this answer is actually for a quiz, but for my opinion and belief, it would be impossible to classify animals and organisms if all of this came from an accident. If this question is for a quiz though, I assume that they will expect you to say False. Mostly to defend their belief. So it's really up to you on what you're gonna go with.
