I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Plastoglobuli (singular plastoglobulus, sometimes spelled plastoglobule(s)), are spherical bubbles of lipids and proteins about 45–60 nanometers across. They are surrounded by a lipid monolayer. Plastoglobuli are found in all chloroplasts, but become more common when the chloroplast is under oxidative stress, or when it ages and transitions into a gerontoplast. Plastoglobuli also exhibit a greater size variation under these conditions. They are also common in etioplasts, but decrease in number as the etioplasts mature into chloroplasts."? 

Plants that are often grown in the dark will likely have which type of organelle instead of the typical organelle that conducts photosynthesis?
