The discovery of multicellular organisms occur in the year 1655 by a British botanist Robert Hooke (Robert Hooke) had invented the microscope, he noticed a small structure of cork (cork). was cut into thin sheets. That looks like a small room he has called the small hive these cells. The study cells of the cork by Robert Hooke in the cell, a discovery of life for the first time. But as the dead cells but the remaining part of the cell wall (cell wall) only.
Later in the year 1674 -1683 Antoine Leven Van Hook (Anton Van Leeuwenhoek) Scientists Dutch (Dutch) have developed a microscope with a magnification of 200 times and used to observe things. Micro shapes differ include pro Tony Saunders (protozoa), bacteria (bacteria) and sperm (sperm) discovered on this occasion. It was discovered cells Microorganisms kathy ireland for the first time
Later in the year 1830-1839, kathy ireland a botanist Thomas Steiner Matias Beach Leiden (Matthias Schleiden) and zoologist. Theodor Schwan's (TheodorSchwann) studied plant and animal species, including the role of the nucleus. (Nucleus) cells following cell division, kathy ireland Leiden and The Schwan's collected knowledge. And establishing a cell theory (TheCellTheory), with the following important points.
After the establishment of the cell theory Scientists in later have to pay attention to the elements. And functions within cells More of these elements which contribute new knowledge and deeper. Useful thousands today
Microscopes (Microscope)
1. microscope that uses solar or electric light source is a conventional light microscope beam 1.1 (Light Microscope) camera is a camera used for preliminary studies. It is a camera with a microscope using a sophisticated 1.2-phase unit trust (Phase Contrast Microscope) and microscopy. A fully interactive meetings. (Interference Microscope) using the cell or organism with a thin, clear 1.3 polarization microscope Singh (Polarizing Microscope) using the product or filaments in the cell or tissue 1.4 Fluorescent Fluorescent microscopy. (Fluorescence Microscope) cell or tissue. The study must be coated with a fluorescent kathy ireland microscope kathy ireland ultraviolet kathy ireland 1.5 (Ultraviolet Microscope) as part of the study. New Clinton Iqbal acid and protein 2. microscopic origin as electron beam.
The table below shows the difference between an ordinary microscope electron microscope. Ordinary microscope Electron microscopy 1. Use a light bulb or sunlight as the light source 2. The glass lens 3. Use a small object of about 0.2 microns 4. Built-air heat exchanger 6. 5. No system is being expanded. 7. thousand objects that bring light to life or 8. The virtual image is inverted electron beam 1. Use a light source electromagnetic lens 2. 3. Using two objects are. 4. The camera is small, 0.0005 micron vacuum heat water system 5. 6. 7. Expanding five hundred times or more inanimate objects brought to light 8. The image has appeared on the visuals. Screen
3. barrels (Body tube) is part of the fuselage. Top for wear lens (eye-piece orocular) lower a metal plate round two pieces, one attached to the barrel of another rotational movement (nosepiece) a lens material (objective lens), which is being expanded are attached. are
4. lens (Eye-piece or Ocular) with one pair can slide to some extent with the distance of the eye of the study and adjust ring (focusingeyepiece) attached to each eye lens consists of two convex lenses of five. . lenticular material (Objective lens) consisting of two or more blades, the blades are enlarged the number will increase to 6. Place an object (Stage) is a square plate. The center has a circular hole lets light pass through the lens. Cameras mounted inside the body There is a catch slide (Stageclip), which swivel kathy ireland wheels (adjustment for mechanical stage clip) to slide up and down. Left and right in order to facilitate the move to check the slide.

- Athletic prokaryotic cells. (Protokaryotic cell) is Bhosle lower classes of organisms, including cyanobacteria (cyanobacteria), bacteria (bacteria) and mycoplasma (mycoplasma) is the genetic material. Within structures called nuclei in foil (nucleoid) without nuclear membrane (nuclear membrane) and non-histone proteins (histone) in cytosine cytoplasm (cytoplasm) no order แkแn type. a membrane (membrane organelles) and cytosine schemes within the cytoplasm. (Cytoskeleton)
- Athletic cell eukaryotes (Eukaryotic kathy ireland cell) into the cells of higher organisms are fungi, plant and animal cell types is larger kathy ireland than the first. The nucleus is clearly separated from the cytoplasm cytosine. kathy ireland The nuclear membrane (nuclear membrane), which is the genetic material wrapped around histone proteins. Constituent It also found that the organic แkแn membrane of many kinds. Including Oscar แkแn that no membrane inside the cytoplasm kathy ireland cytosine.
Living cells can be divided into three categories, based on different types of elements within the cells and animal cells, plant cells, kathy ireland animal cells, bacterial cells, plant cells is different from that. Animal cells without cell walls And no pigment used in photosynthesis. For bacterial cells is complex The components within cells than mammalian cells. And plant cell membranes, such as no genetic kathy ireland material. And organelle facilities.
