An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. It is a special type of microscope having a high resolution of images, able to magnify objects in nanometres, which are formed by controlled use of electrons in a vacuum captured ...
Base: The bottom of the microscope, used for support. Illuminator: A steady light source (110 volts) used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. ...
Cancer cells look different. Under a microscope, cancer cells may look very different from normal cells. They often have different sizes and some may be larger than normal while others are smaller. Cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may ...

aSnapshots of monolayer bacterial swarms with different aspect ratios and densities, representative of the motile phases. Colors represent moving clusters (gray or non-labeled cells are not moving). The scale bar corresponds to 50 μm. For short cells (S phase), almost all cells are moving ...
What is a simple microscope? Explain with a labeled diagram the working of a simple microscope. What is free potential? Describe with the aid of a fully labeled diagram the features and their uses of a bicycle pump. Explain Lenz's law (provide diagrams). What is free energy? How...
The structure of these areas of the organelle reflect their special roles within the cell. Under a microscope's lens, the phospholipid membrane of the rough endoplasmic membrane appears covered in dots or bumps. These are **ribosomes**, which give the rough endoplasmic reticulum a bumpy or ...
extended by additional imaging of the same serial sections. The images were acquired using a Zeiss Field-Emission Scanning Electron Microscope using WaferMapper software65. Only a few tens of neurons had been manually reconstructed in our original publication on the ssEM dataset in Vishwanathan et ...
The cell is the basic unit of life. All organisms are made up of cells (or in some cases, a single cell). Most cells are very small; in fact, most are invisible without using a microscope. Cells are covered by a cell membrane and come in many different shapes. The contents of a ...
