the development of the light microscope many scientists were able to view microscopic objects such as cells. The first to accomplish this was Robert Hooke when he used a light microscope to observe a thin slice of cork. Hooke observed that the cork was made of tiny structures of which he called cells. Hooke was in fact looking at the cell walls of dead plant cells that make up the cork. After Hooke‚ a Dutch scientist named Anton van Leeuwenhoek used the light microscope to observe living cells inside

Microscopes were invented in the 1600s. Robert Hooke first looked at a thin slice of cork in 1665; he saw "a lot of little boxes." These little boxes first reminded of the little rooms monks lived in‚ so he called them cells. Hooke observed the same pattern in the stems and roots of carrots and other plants. What Hooke still did not know‚ however‚ was that cells are the basic units of living things. Ten years later‚ the Dutch scientist Anton van Leeuwenhoek focused a microscope on what seemed to

Asses the impact of the development of the electron microscope on our understanding of the cell and it’s role in cell theory. Since the invention of the electron microscope in 1928 scientists have been able to study the ultrastructure of cells‚ that is‚ parts smaller than what can be seen with a light microscope‚ otherwise known as organelles and their functions. Light microscopes had been developed to a point where the quality of the lenses was not limiting the detail in the image‚ the main

electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities between light microscopes and electron

How microscopes have contributed to our understanding of living organisms There are 2 types of microscopes these are; light microscope and electron microscope. Light microscopes use a beam of light however the resolution is lower than the electron microscope so the image is not clear‚ however they can view living organisms. These types of microscopes are used in schools to view simple cellular structures‚ which is good to teach simple biology Mitosis and meiosis can be seen with light microscopes

Since Galileo began using a rudimentary compound microscope in 1609‚ whole new ranges of objects not known to even exist were discovered from that basic piece of technology. The microscope played the key role in discovering cells‚ and as it advanced with technology‚ so too did the cell theory. In 1665‚ scientist Robert Hooke used a microscope to look at slices of cork. He noticed that the cork was divided up into hundreds of tiny little compartments that he named cells. Hooke was the first person

Aim: To observe and draw transverse sections of parenchyma‚ collenchyma‚ sclerenchyma‚ xylem‚ phloem and epidermal cells using a light microscope. Apparatus and Materials: Light microscope; microscopic slide of dicotyledonous stem Method: 1. The light microscope was plugged into a power source‚ and switched on. 2. The coarse focus of the light microscope was adjusted with both hands to move the stage downwards. 3. The slide with the dicotyledonous stem section was placed on the stage
