Cell OrganellesCell Organelles

Like a major city, a cell teems with specialized workers that carry out its daily operations—making energy, moving proteins, or helping with other tasks. Researchers took microscopic pictures of thin layers of a cell and then combined them to make this 3-D image featuring color-coded organelles—the cell’s “workers.”
