Microscope are useful in viewing the letter “e” and the cheek cells. It shows a close visual image, which help to observe the two objects. Following the methods is important, because it provides the necessary materials and the steps of the procedure. It’s extremely important to wear a apron , goggles, and gloves. Also, be cautious in using the materials. The purpose is to observe and how to use the microscope under the specimen. For the results each figure image shows the differences between the low-power and the high-power objectives. In those figure, it will explain the view of the image of a cheek cells and a close image of how does the letter “e” looks like.
Introduction
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.

...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.
The procedure starts with the preparation of the frog and the set-up of the equipment. During the remainder of this lab, continuous
The hyperplasia foci can be seen as early as 2 months, as depicted by the histological picture. The number of cells with hyperplasia is then
Moreover, I will let the patient become familiar with any instruments such as a speculum, and demonstrate the tools that will be used to obtain tissue samples that would be used during the examination. Explaining the procedure is also a significant step; this will allow the patient have a sense of control during the examination as we ask and answer questions about their current state, that would help disseminate any concern they may have. Meanwhile, they can learn about what may happen, related to any body sensations or feelings they can experience during the procedure, all while the provider continues to develop rapport and patient’s trust

An inspection of the modern animal phyla will reveal that eyes are just as diverse as they are complex. Some organisms like the rag worm have pigmented cup eyes while other like he box jellyfish have two lens eyes and two pairs of pigment pit eyes. To account for the diversity in eye structure, we must first examine the eye ‘prototype’, the original structure that was acted upon by evolution. The simplest organ that can be considered an eye is composed of a single photoreceptor cell and a single pigment cell, without any lens or other refractive body (Arendt, 2003). Such organs are know as eyespots, and...

Microvilli and cilia play a major role in many important biological processes in mammalian cells. They are very small, intricate structures found lining the cells in the body and can only be viewed under a microscope. Microvilli has been derived from the Greek word mikros, meaning “small” and the Latin word villus, meaning “hair”. Cilia means “eyelashes” in Latin(1). They are both types of projections in the plasma membrane, however, only cilia can move(2).
A small drop of venous blood is placed on a glass of microscope slide, using a disposable pipette. Used a wooden applicator stick for this purpose
There are three simple tissues namely, parenchyma, collenchyma, and sclerenchyma. Parenchyma is thought of as the ground tissue of an axis since it occurs in greatest abundance and is the tissue in which the vascular tissues are embedded. Parenchyma cells may be isodiametric in both the pith and the cortex, but are more mostly longitudinally elongated in the cortex. They have comparatively thin walls. Wall layers are continuously shaped regions. These simple pits usually occur opposite each other, forming pit-pairs in the walls of contiguous cells. Plasmodesmata (specialized strands of endoplasmic reticulum) form interconnections with the protoplasts of adjacent living cells through simple
Histopathological samples are examined in vivo where the relationship between the cells is maintained and observable. These can be cross sections of small organs or slices of larger ones. This results in a large number of cells being available and their cell-to-cell interactions apparent for examination.
In 1898, Camillo Golgi developed a staining technique using silver nitrate that allows the identification of the cellular organelle that now bears his name, the “Golgi apparatus.” The Golgi apparatus is responsible for processing the proteins that are synthesized in the endoplasmic reticulum.
The origin of the biological term cell came from Robert Hooke in 1662. He observed tiny compartments in the cork of a mature tree and gave them the Latin name “cellulae”, which translates into “small rooms”. In the late 1680s, Anton Van Leeuwenhoek was the first scientist to actually lay eyes on a cell. Before, there had been theories of “cells” but no one had the technology to see something so microscopic yet. Van Leeuwenhoek ran a draper 's shop and wanted to see the quality of the thread, better than the magnifying lenses available at that time. Therefore, he began to develop an interest in lens-making, with an interest already in microscopes and a familiarity with glass
