READ THE TEXT AND ANSWER THE QUESTION “During a science experiment, a student placed a green leaf under the sun and observed bubbles forming on its surface. These bubbles were caused by the process of photosynthesis.” 6. WHICH ORGANELLE IN PLANT CELLS IS RESPONSIBLE FOR THIS PROCESS?. A. Nucleus, because it stores DNA. B. Mitochondria, because it creates energy from food. C. Chloroplast, because it captures sunlight to make food. D. Vacuole, because it stores water and nutrients.

READ AND ANSWER “Scientists believe that mitochondria and chloroplasts were once independent bacteria that became part of early eukaryotic cells. This idea is known as the endosymbiotic theory.” 9. WHAT SUPPORTS THE ENDOSYMBIOTIC THEORY?. A. Chloroplasts are only found in animals. B. Mitochondria and chloroplasts have their own DNA. C. Mitochondria are made of lipids and sugars. D. Prokaryotes have a cell wall and a nucleus.
