Functions Of A Compound Microscope

Without the cells there will be no life. A cell is the the building block of the body. There 2 different types of cells there are animal cell and plants cells. Eukaryote is any cell that has a cell membrane bound. It also contains organelles.

Concept 6.1 Biologists use microscopes and the tools of biochemistry to study cells 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference. Magnification is the ratio of an object’s image size to its real size. Resolution is a measure of the clarity of the image; it is the minimum distance two points can be separated and still be distinguished

Preparing specimen for electron microscope hard, light microscope still very useful as a window on living cells.

The illuminating parts of a microscope enable us to see the detail of the subject placed under the microscope. The three main parts that enable us to do this are: the condenser which illuminates the object that is placed under the microscope, the objectives which forms the magnified image, and the eyepiece which enables us to see the magnified

How should the unknown microscopic organisms be classified? The concept of the experiment was to conduct a systematic observation about the traits of unknown organisms, and classify them to the right group. Making detailed observations about the traits, made it possible to identify which cell the trait belonged to because different cells have different traits. Animal cells do not have a cell wall, and has one or more small vacuoles. Plant cells has a cell wall, rectangular (fixed shape), and has a chloroplasts. Cytoplasm, Endoplasmic Reticulum, Ribosomes, Mitochondria, and Golgi apparatus to name a few.

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

Using the microscope provided to analyze the different size of the different cells and organisms

It was then during the 1950’s that Zacharias Jansen and his father, Han Jansen, created the first high-powered compound light microscope. Images could be magnified up to 9x which was a novel feat at that time. Zacharias and his father created the device after experimenting with glasses and discovered that by placing multiple lens in a tube they could increase magnification. Unfortunately, the microscope lacked the high resolution we have come to expect in modern-day light microscopes. The images produced by the Hans’ primitive microscope was extremely blurry and had limited

The purpose of this lab was to practice proper handling of the light microscope, learn the names and functions of the light microscope parts, acquire skill in using the light microscope by carefully following all directions, prepare a wet mount, and locate objects under low and high power magnification. In addition, we will learn to position objects when viewed with a microscope, adjust the diaphragm correctly to achieve proper light under low and high power, learn to locate objects at various places in the “depth of field” and use stains (iodine) as an aid.

The purpose of this lab is to insure that all students understand how to correctly use the microscope. Students will all learn proper care and handling of the microscope, as well as learning the correct way to look at slides and specimens through the microscope.

This experiment was about using the microscopes and trying to adjust the objective lens until I was able to see the cells through the ocular lens.

Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryotic means 'pre-nucleus' and eukaryotic means 'true nucleus'.

There were many tiny cells, but they were very hard to see. The cells were dark and clumped together.

B. Label the diagram of the pocket microscope in Figure 4. Use the following terms: eyepiece,

Some are so large that they are housed in silos several stories high while others are small enough to fit in the palm of a hand. These instruments have given scientists a new look at the world around us.
