What are Light Microscopes? 

What does the word microscope mean:  The first part of the word “Micro” means tiny. The “scope” part means to look at or view.  Microscopes are tools that are used too enlarge images of small objects so that they can be studied.

A light microscope is an instrument made up of two lens they are eyepiece lens and the object lens combined they produce a much greater magnification that what is possible with just one single lens. The microscope also has a variety of knobs to focus the picture seen thought the microscope.  The light microscope is also known as the compound microscope this is because it uses more than one lens.

The light microscope uses visible light to detect small objects; the microscope consists of an optical instrument that magnifies the image of an object.  It is probably the most used research tool in biology. The total magnification is calculated by multiplying the magnification of the two lenses inside the microscope.  Images looked at under the light microscope are reversed and inverted.

Cytoplasm: is a partly fluid material, which can flow slowly and in which many other substances are suspended such as large fat and protein molecules. Many of the chemical reactions take place in the cytoplasm, which will provide the cell with energy and allow it to build up larger molecules that it needs. Studying the cell further and using better more powerful microscopes has shown that the cytoplasm actually contains lots of small structures called organelles. These have different roles and separate the reactions. In a cell. Examples are mitochondria where energy is released and ribosomes where proteins are ...
