Scanning Electron Microscope: A type of microscope that uses electrons instead of light to form an image of the sample, providing detailed three-dimensional images at high magnifications. Transmission Electron Microscope: A type of microscope that uses a beam of electrons to create an image of the specimen, allowing for very high-resolution imaging of the internal structure of cells and molecules. 3D Image: A visual representation that provides the perception of depth, creating the illusion of three-dimensional space on a two-dimensional surface. Organelles: Specialized structures within a cell that perform specific functions, like mitochondria for energy production and ribosomes for protein synthesis.
