It’s sending electrical impulses, pumping blood, filtering urine, digesting food, making protein, storing fat, and that’s just the stuff you’re not thinking about! You can do all this because you are made of cells - tiny units of life that are like specialized factories, full of machinery designed to accomplish the business of life. Right now your body is doing a million things at once. You can also explore the structures of an interactive animal cell at this link. Like Jell-O containing mixed fruit, the cytoplasm of the cell also contains various structures, such as a nucleus and other organelles. Its basic structure is a plasmamembrane filled with cytoplasm. In some ways, a cell resembles a plastic bag full of Jell-O. What similarities and differences do you see? Compare and contrast the eukaryotic cell shown here with the prokaryotic cell. Ribosomes, the organelle where proteins are made, are the only organelles in prokaryotic cells.Įukaryotic Cell. This allows eukaryotic cells to have greater cell specificity than prokaryotic cells. Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Organelles called mitochondria, for example, provide energy to the cell, and organelles called vacuoles store substances in the cell. An organelle is a structure within the cytoplasm that performs a specific job in the cell. Organisms with eukaryotic cells are called eukaryotes, and they range from fungi to people.Įukaryotic cells also contain other organelles besides the nucleus. Eukaryotic cells are usually larger than prokaryotic cells, and they are found mainly in multicellular organisms. A typical eukaryotic cell is shown in Figure below. \)Įukaryotic cells are cells that contain a nucleus.
