A microscope is essential for the study of histology. It is used to magnify and visualize the cellular and tissue structures that are being examined under high magnification.
The highest magnification microscope generally used to study cells is the electron microscope, which can magnify objects up to 2 million times. This type of microscope allows for very detailed imaging of cell structures and organelles that are not visible with lower magnification microscopes.
An electron microscope, specifically a transmission electron microscope, would be used to study a specimen smaller than 0.2 micrometers. This type of microscope uses a beam of electrons to create high-resolution images of tiny structures at the nanometer scale.
You would typically use an electron microscope to study the internal parts of a cell, as it provides much higher magnification and resolution compared to a light microscope. Electron microscopes can reveal detailed structures inside cells, such as organelles like mitochondria and the nucleus.
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
A biologist would likely use an electron microscope, specifically a scanning electron microscope (SEM), to study the protein molecules on the surface of a cell. The high magnification and resolution of an SEM allow for detailed imaging of protein structures at the nanometer scale.
A compound light microscope would be the most suitable choice for observing a living amoeba. This type of microscope allows for observation of live specimens under magnification, while also providing enough clarity to study cellular structures.
Histology, the study of tissues and cells, often requires magnification to study because the structures being examined are very small and intricate. Magnification allows for better visualization and understanding of these microscopic features.
Specimen magnification on a microscope is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens. For example, if the eyepiece magnifies 10 times and the objective lens magnifies 40 times, the total magnification would be 10 x 40 = 400 times.
For determining species and investigating all the fine features of spiders, it is often helpful and sometimes necessary to get magnification. Sometimes a hand magnifying glass will provide sufficient magnification. Sometimes an electron microscope is needed to see the finest structures.
