The nucleus controls the cell like an office, the nucleolus makes ribosomes like a principal, and chromosomes pass information from parent to offspring like teachers pass knowledge to students. The cell membrane gives shape like walls, cytoplasm allows chemical reactions like a chemistry room, vacuoles store nutrients like a cafeteria, mitochondria produce energy from food like a gym, and ribosomes make protein like the food we eat. Organelles connect areas of the cell like halls connect school rooms.
