D. lysosomes, vacuoles, plasma membrane vacuoles, mitochondria, plasma membrane lysosomes, vacuoles, nuclear membrane all intracellular organelles and membranes

According to the endosymbiont theory, which of the following organelles were once endosymbiotic prokaryotic organisms? A. B. C. D. Mitochondria and lysosomes Mitochondria and chloroplasts Chloroplasts and Golgi apparatus and ribosomes

Which of the following is not an argument for theory that mitochondria and chloroplasts evolved from prokaryotic endosymbionts? A. B. C. D. Mitochondria and chloroplasts have double membranes. Mitochondria and chloroplasts have their own ribosomes. Mitochondria and chloroplasts have their own DNA. All of the above support the endosymbiotic theory.
