Download file to see previous pages This lab successfully taught me the size variation between cells based on microscopic measurements. The sized of different cells were estimated .Therefore I could understand how life thrives even in the smallest of cells.

Moreover, based on study of the different types of cells I can now classify cells according to Prokaryotic or Eukaryotic origin. I also gained an understanding of the difference between plant and animal cells on basis of their structural features at the microscopic level.

The lab helped to see the growth bacteria on nutrient medium by the binary fission process and understand the rapid increase in bacterial population. Besides this, processes like mitosis and meiosis were also thoroughly understood based on the stages where mitosis helped in production of autosomes while meiosis produced gametes. The mechanisms of each were also understood.

The basic difference between mitosis , meiosis and binary fission is that Mitosis consists of 4 stages (prophase, metaphase, anaphase, telophase) while Meiosis consists of Mitosis and 4 more stages ; however binary fission does not consist of any such stage,

Photosynthesis and cellular respiration are remarkably different. The reactant or raw materials of respiration are glucose and oxygen while that of photosynthesis is carbon dioxide, water and energy. Photosynthesis can take place only in the presence of sunlight hence only during day however, respiration can occur all throughout the day.
There is an ecological relation between cellular respiration and photosynthesis. Both help to balance the ecology of life on Earth. Cellular respiration releases carbon dioxide into the atmosphere. However this carbon dioxide serves as the raw material for photosynthesis hence there is no net increase in carbon dioxide or accumulation of the gas in the atmosphere at all. ...Download file to see next pagesRead More

Electron Microscopy

...and spatial resolution < 2nm (that means 3 or 6 times better than SEM) (Polytechnic of Turin) FESEM produces clearer, less electrostatically distorted images with spatial resolution down to 1 1/2 nm. That's 3 to 6 times better than conventional SEM. Smaller-area contamination spots can be examined at electron accelerating voltages compatible with Energy Dispersive X-ray Spectroscopy. Reduced penetration of low kinetic energy electrons probes closer to the immediate material surface. High quality, low voltage images are obtained with negligible electrical charging of samples. (Accelerating voltages range from 0.5 to 30 kV). Need for placing conducting coatings on insulating materials is virtually eliminated. For...

Electron Microscopy

...Electron Microscopy la. Briefly describe how the main lens aberrations arise in electron microscopy. Electron microscopy is a technique in microscopy that offers higher magni-fication, higher resolution and greater depth of field in viewing objects. When the main lens aberrations arise in electron microscopy1 the high quality of resolution, light focusing to the point of object and depth of field is not achieved. Lens aberrations can exist in a form of chromatic aberrations. This exist when a range of wavelengths is instantly present in the light (for example in 'white' light) and occur because a single lens will enable light to be diverted by an amount...

Transmission Electron Microscopy

...? Transmission Electron Microscopy has revolutionized the field of microscopy, touching a variety of aspects, both biological and physical. Transmission Electron Microscopes (TEMs) comprise a range of different instruments that make use of the properties of electrons, both as particles and as waves. The TEM generates a tremendous range of signals so we can obtain images, DPs and several different kinds of spectra from the same small region of the specimen (Williams and Carter 2009). The working principle of a TEM is that when electrons are accelerated up to high energy levels and then focused onto a specimen, they scatter or backscatter elastically or in-elastically, producing many different interactions...

Low Voltage Scanning Electron Microscopy

... Low Voltage Scanning Electron Microscopy Low voltage scanning electron microscopy denotes the use of scanning electron microscopy, which uses few kilo electron-volts (<5 keV) for accelerating the electron beam used in scanning. Low-voltage electron microscopes (LVEM) have proven to be effective in comparison to High-voltage electron microscopes (HVEM). Both types of microscopes work on the same principles, but the significant different between them results from the effect of electron acceleration voltage variation, which is applied in their respective designs (Schatten & James, 2007). Working Principles of Scanning Electron Microscopy (SEM) Scanning electron microscopes (SEMs) are microscopes, which produce sample images by scanning... from the projected beam as well as density and atomic number of the material under observation as the sample. Technically, the differences between HVEM and LVEM are a result of differences in landing energy determined by the electron accelerating voltage. The acquired signals are detected and amplified to develop images. The differences of detected signals are represented by variations in brightness on the visual display. The resultant image is thus a representative of electron energy emitted from the sample’s surface through inelastic and elastic scattering. The...

The attachment of my child with me and my partner appears to be developing somewhat in line with the natural process of fondness. According to Bowlby attachment is basically characterised by (Wagner, 2010); Proximity Maintenance Safe...

...-antibody conjugate is washed and removed, only those microbial cells will fluoresce, can be located and identified by epifluorescence microscopy. A recent method uses monoclonal or polyclonal antibodies. Certain other methods like Enzyme-linked immunosorbant assays (ELISA assays) and the Polymerase Chain Reaction (PCR) methods can also used to detect the microbes in soils (Source - United Nations Water Virtual Learning Centre). Isolating bacteria and viruses or virus like particles (VLP) from the soil samples is being investigated through two techniques i.e., Epifluorescence Microscopy [EFM] and Transmission Electron Microscopy [TEM] using two elution...

An Atomic Force Microscopy is a device that can analyse the characteristics of a material at microscopic level and classify it. It enables one to view a material with good precision ranging between 100 micrometre and 1 micrometre. The instrument operates by allowing an exceptionally sharp and thin tip to get into contact with the surface or be in very close proximity to the surface whose characteristic is to be determined. The tip is a few microns in length and of small diameter, about 100A in diameter. This tip is attached... constant...

Scanning Tunnelling Microscopy

...Scanning Tunnelling Microscopy 1. Abstract Novel technologies to observe the structure of matter at an atomic scale have enabled researchers to gain a better understanding of the processes at work on the atomic scale. This has enabled newer developments such as the miniaturization of computer chips, creation of quantum computing and the development of nano electronics. More and more computing power can now be developed onto the same sized chips as before while innovative aspects of processing instructions and storing data are also in development. The heart of this development lies in the ability to monitor developments at the atomic scale. Since the inception of such technology (namely scanning probe...
