Final answer:
The scanning electron microscope (SEM) creates highly detailed three-dimensional images of cell surface characteristics, while the transmission electron microscope (TEM) provides details of a cell's internal structures. SEM allows for the visualization of surface shape and texture, while TEM allows for the visualization of internal organelles and membranes. SEM images have a three-dimensional appearance, while TEM images have a two-dimensional appearance.
Step-by-step explanation:
In a scanning electron microscope (SEM), a beam of electrons moves back and forth across a cell's surface, creating details of cell surface characteristics. The images produced by SEM are highly detailed with a three-dimensional appearance, and they are typically displayed on a monitor. On the other hand, in a transmission electron microscope (TEM), the electron beam penetrates the cell and provides details of a cell's internal structures. TEM allows for the visualization of internal organelles and the interior of membranes.
SEM allows scientists to find the shape and surface texture of extremely small objects, while TEM provides a view of a cell's internal structures. SEM images typically have a three-dimensional appearance, while TEM images have a two-dimensional appearance. Furthermore, SEM images can be magnified up to 500,000 times, while TEM images can achieve much higher magnification, up to 2,000,000 times.
Overall, while SEM is used to view surfaces of objects, TEM is used to visualize internal structures of cells and organelles.
