My research focused on mathematical modeling of the cell cycle in leukemia and involved experiments with cell lines. During that time, I had to count cells with a hemocytometer so often to track growth that I got tired and decided to build an app, HemocyTap , and share my knowledge on the topic here to help as many people as possible. A — Eye piece lens. This is where you position your eyes to look into the magnified sample. It usually has a magnification of 10X check your microscope. B — Objective lens. This lens does most of the magnification job, simpler compound microscopes have only one magnification cannot be changed or they have several usually: 4X, 10X, and 40X although other magnifications are possible within that range; X magnification is only possible with oil immersion.
A compound microscope is an instrument that is used to view magnified images of small objects on a glass slide. It can achieve higher levels of magnification than stereo or other low power microscopes and reduce chromatic aberration. It achieves this through the use of two or more lenses in the objective and the eyepiece. The objective lens or objectives located on the nosepiece have a short focal length and are close to the target object where it collects light and focuses the image of the object into the microscope. The second lens, in the eyepiece, has a longer focal length and further enlarges the image. Each part of the compound microscope serves its own unique function, with each being important to the function of the scope as a whole.

Cells are the basic units of life. All living things are made of cells. All cells are produced from existing cells. How do you know that a cell is a prokaryote when looking through a microscope? What can a single cell organism like an amoeba accomplish? In a multicellular organism, what are the levels of organization from simplest to most complex?
Looking at different types of plant cells through a microscope, you see a bunch of undifferentiated cells that have lots of chloroplasts and are used for food.

NCBI Bookshelf. Molecular Biology of the Cell. New York: Garland Science; It was not until good light microscopes became available in the early part of the nineteenth century that all plant and animal tissues were discovered to be aggregates of individual cells. This discovery, proposed as the cell doctrine by Schleiden and Schwann in , marks the formal birth of cell biology. Animal cells are not only tiny, they are also colorless and translucent.
