Anton Von Leeuwenhoek was the inventor of the microscope and brought the discovery of biology. He introduce in how the microscope is being function and the use of the magnification lenses. For the lab, the microscope should be carry by the arm and the base. The objective lenses needed to be at low-power and gradually switch to the high-power. To focus on a specimen, gently move the coarse or the fine adjustment knob. Later, total the magnification of the ocular lens times by the objectives lenses.
In the letter “e” and the cheek cells, the primary focus for the lab is using the proper technique in using the microscope. Drawing the visual image and identifying the parts. Knowing in how to get the total magnification for the samples. The letter “e” is being cut off by a newspaper article and the cheek cells is coming from the inside of the mouth. Both of the specimen is being observed to see any differences between in a low-power and a high-power objective.
Materials to use:
* A Microscope

...t the letter “e” and the cheek cells. For example, in the letter “e”, the ink under the microscope is thin and dull. Comparing a normal view, the ink is thick and dark. The letter “e” is being thin, because it gives a clear details of what the newspaper letter “e” looks like. When moving the slide to the right. Looking through the ocular lens, it moved toward the left. The letter “e” moves toward the opposite direction. When the slide is moved to the left, up and down.
In the cheek cells, the methylene blue helped to identify the visual details of the cheek cells. Also, in how to focus the image in using the coarse and the fine adjustment knob. Drawing the images and place it on figures 1-5 it indicate the drawing , the magnification and the labeling. Knowing how to use the microscope functions and properties. The results of the lab activity was a success.

- ... Most of the chemical reactions of the cell take place in the cytoplasm. The “powerhouse” or the “energy generators” of both plant and animal cells are the mitochondria. These substances convert the sugar and other organic molecules in the cell to produce ATP (adenosine triphosphate) – required as a source of energy for the chemical reactions of a cell. Furthermore, both cells have a cell membrane. The cell membrane is like the guard to a cell and controls what enters and leaves it. It is responsible for the absorption of important nutrients (e.g.... [tags: structures, cells, powerhouse]

- Human Embryonic Stem cells and Induced Pluripotent Stem Cells are two modern methods of research; and treatment being aimed at the treatment of cancer, and many degenerative and genetic diseases. Stem cells are cells with the ability to develop into a cell of a different type, some types of stem cells are able to differentiate or change into a cell which is specific and functional to a specific tissue or organ system. This unique ability is what many scientists are trying to focus towards regeneration of different tissues, or the creation of new tissue to help cure, or treat diseases like cancer, multiple sclerosis, and alzheimer's....

- A Comparison of Eukaryotic and Prokaryotic Cells There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life. Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm.... [tags: Biology, Cells, Science]

- Introduction Cells communicate by transferring molecules from one to another. When a molecule is transferred it creates a reaction which then causes an effect. Within multicellular organisms there is cell-to-cell communication. Direct communication between cells can occur in two ways. One way is cell-cell recognition via interaction between surface proteins. When there is contact between cell surfaces, the proteins on the surface of the cell interact and create a signal. The other way is through cell junctions between adjacent cells.... [tags: molecules, cells, plasma membrane]

- Plant and Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cells are placed in the two categories, what is inside the cell must first be looked at.... [tags: Biology Biological Cells Essays]

- Characterization through Imagery and Metaphor in The Scarlet Letter Throughout his novel, The Scarlet Letter, Hawthorne reveals character through the use of imagery and metaphor. In the first Chapter of The Scarlet Letter, "The Prison-Door", the reader is immediately introduced to the people of Puritan Boston. Hawthorne begins to develop the character of the common people in order to build the mood of the story. The first sentence begins, "A throng of bearded men, in sad-colored garments and gray, steeple-crowned hats, intermixed with women, some wearing hoods, and others bareheaded, was assembled in front of a wooden edifice, the door of which was heavily timbered with oak, a...

- Liberation from Sin through Pearl in The Scarlet Letter 'This child ... hath come from the hand of God, to work in many ways upon her heart ... It was meant for a blessing, for the one blessing of her life. It was meant, doubtless ... for a retribution too; a torture to be felt at many an unthought-of moment; a pang, as sting, an ever-recurring agony, in the midst of a troubled joy!" (Hawthorne 105) This, as Arthur Dimmesdale almost prophetically expresses in the early scenes of Hawthorne's The Scarlet Letter, was the role of Pearl, the elfish child borne of his and Hester Prynne's guilty passion....

- The Scarlet Letter: Dimmesdale – Purification Through Death Although Nathaniel Hawthorne’s The Scarlet Letter is primarily the story of an adulteress atoning for her sin and conquering the insignia which brings torment to her spirit, the quest of the partner in her sin, Arthur Dimmesdale, is no less important and even more painful. His quest, simply phrased, is to glorify God through his priesthood and expiate his sin of adultery - to save his soul - while protecting his reputation. To do so, he tries to continue day by day to do the work of the Lord which he so loves, while relegating to the darkest, most secret recesses of his heart the crime which he so hates. Only in private does... [tags: Scarlet Letter essays]
