The cell theory holds true for all living things, no matter how big or small, or how simple or complex. Since according to research, cells are common to all living things, they can provide information about all life. And because all cells come from other cells, scientists can study cells to learn about growth, reproduction, and all other functions that living things perform. By learning about cells and how they function, you can learn about all types of living things. Over time, and with the development of the electron microscope, the theory has continued to evolve. As more and more living material has been observed at higher and higher magnifications, much more has been learned, leading to the modern cell theory. The modern cell theory includes the basic components of the classic cell theory and then adds more… Modern Interpretation of the Cell Theory 1. 2. 3. 4. All known living things are made up of cells. The cell is structural & functional unit of all living things. All cells come from pre-existing cells by division. Cells contain hereditary information which is passed from cell to cell during cell division. 5. All cells are basically the same in chemical composition. 6. All energy flow of life occurs within cells. MICROSOPE A microscope (from the Greek “mikrós” meaning "small" and “skopeîn” meaning “to look”) is an instrument to see objects too tiny for the naked eye. Microscopes can be separated into optical theory microscopes, electron microscopes, and scanning probe microscopes. The most common type of microscope—and the first invented—is the optical microscope. This is an optical instrument containing one or more lenses producing an enlarged image of an object placed in the focal plane of the lenses.

Compound Light Microscope The compound microscope uses lenses and light to enlarge the image. It is also called an optical or light microscope. The compound microscope has two systems of lenses for greater magnification: 1. the ocular, or eyepiece lens that one looks into, and 2. the objective lens, or the lens closest to the object.
