How do we see inside cells?
Fluorescence microscopes allow us to see fluorescent molecules such as different stains which bind to different parts of the cell enabling us to see them clearly. A more advance system is known as a confocal laser scanning fluorescence microscope and is in essence a much further developed light microscope.
How can we see the cell?
Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter they can be observed by light microscopy as can some of the larger subcellular organelles such as nuclei chloroplasts and mitochondria.

Mitochondria have a distinctive appearance when viewed by electron microscopy. They often appear as rounded or sausage-shaped structures (Figure 1a b and Figure 22a b) measuring about 0.5-1.0 µm in diameter and 2-8 µm in length although their size and shape vary and they are often much bigger in plants.

Where is the mitochondria in a cell?
Each cell contains hundreds to thousands of mitochondria which are located in the fluid that surrounds the nucleus (the cytoplasm). Although most DNA is packaged in chromosomes within the nucleus mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.
Are cells alive?
Cells are sacs of fluid surrounded by cell membranes. … But the structures inside the cell cannot perform these functions on their own so the cell is considered the lowest level. Each cell is capable of converting fuel to useable energy. Therefore cells not only make up living things they are living things.
