Final answer:
Granules and supergranules are structures observed on the sun's surface, specifically in the photosphere. They have different sizes and lifetimes, with granules being smaller and shorter-lived compared to supergranules.
Step-by-step explanation:
Granules and supergranules are both structures observed on the surface of the sun, specifically in the photosphere. Granules are bright areas surrounded by darker regions and have a diameter of 700 to 1000 kilometers. They last for 5 to 10 minutes. Supergranules, on the other hand, are larger, about 35,000 kilometers across, and last about 24 hours. Both of these structures are part of the granulation pattern observed on the sun's surface.
