Can you tell me the sizes of cell organelles in micrometers and nanometers?

Cortical neurons average about 30 microns in a cell culture-somewhat smaller in a brain section.  Hippocampal pyramidal neurons run approximately 40-50 microns, and spinal motorneurons run up to about 80 microns. (If you are working with cortical and striatal neurons, you will likely branch out into hippocampal neurons at some point.) Scanning electron microscopy gives a volume/diameter ratio that indicates a hemispherical shape in cultured neurons, thus the formula would be 0.5 X spherical volume, or:\n(((4 pi)/3)) X  radius cubed) X ).5.  Simplified it would be 2/3 pi X radius cubed.  Thus a largish cortical neurons of diameter 40 microns (40 X 10-6 M) would have a volume of approximately 17000 cubic microns.  Since a mm3 contains 1 billion cubic microns, the volume would be 0.000017 cubic mm, or  0.000000017 ml (a ml contains 1000 mm3).  Thus it would take about 50 million cortical cells to make 1 ml of cells.  When we pellet neurons, we find about 2-4 million cells per 100 ul, so the calculation is good to a factor of 2 or so.

Plant cells have Chloroplast... Cell Walls... and Water Vacuoles\n\nAnimals cells... of a centrioul, and food Vacoules.\n\nThose are the main differences of the organells

Microtubules are protein structures found within cells, one of the components of the cytoskeleton. They have diameter of ~ 24 nm and length varying from several micrometers to possibly millimeters in axons of nerve cells. Microtubules serve as structural components within cells and are involved in many cellular processes including mitosis, cytokinesis, and vesicular transport.

Many ways.\n\nPlants would have organelles specific to a plant and would be a rectangular shape with 2 nuclei during cytokinesis\n\nanimal would have no chroloplasts and would be oval because the nuclei push as far apart as possible and the animal cell is flexible, not rigged like a plant.

1 micrometer = 1x 10^-6 m\n                      = 1x 10^-4 cm\nhope that helps(:

For part 1, if the cell's diameter was 1/15 of the total field, and the field was 450 microns across, then the cell's actual diameter was 450 microns/15 = 30 microns = 3 * 10^-5 meters.\n\nThe diameter of this cell in the drawing is 0.5 cm = 5*10^-3 meters.  This drawing therefore has a magnification of (5*10^-3)/(3*10^-5) = 166.6666666...times.\n\nFor part 2, The magnification is given by (size in image)/(actual size), so we have that 45000 = (1.5 mm)/a, where "a" is the actual thickness.  Solving for a, we get a = 1.5mm/45000 = 3.333*10^-8 meters = 33.3 nanometers = 0.0333 microns.\n\n-----------------------\n\nAs for the question posed in the "additional details", when the magnification of a microscope is increased, the diameter of the field being imaged decreases (choice "A").

neurons come in many different sizes but you can assume the cell body of one neuron is 10 microns wide.  Some neurons are very short...less than a millimeter in length. Some neurons are very long...a meter or more! The axon of a motor neuron in the spinal cord that innervates a muscle in the foot can be about 1 meter (3 feet) in length.  http://faculty.washington.edu/chudler/what.html\n\nMost plant cells range in size between 10 and 50 micrometers.\nhttp://www.beyondbooks.com/lif71/4.asp

Organelles don't have much of an effect on cell function--mostly it's its shape. More active cells are smaller than less active cells so information can quickly pass through the cytoplasm and into the nucleus. This explains why muscle cells are long, small and slender, and fat cells are large and bulky. \n\nThe membrane of smaller cells has many exterior folds to increase its surface area and ablitily to collect nutrients necessary for cell function.

Cells are not all of the same size, but average size is close to 15 micrometers.

Try a Yahoo search for parts of a microscope\n\nFound several sites that look useful:\n\nAn online "flashcard" quiz to practice naming the parts:\n\nhttp://biologycorner.com/microquiz/\nhttp://www.cas.muohio.edu/~mbi-ws/microscopes/microscopeparts.html\n\n\nDiagrams with labels:\n\nhttp://www.usoe.k12.ut.us/curr/science/sciber00/7th/cells/sciber/micrpart.htm\nhttp://www.middleschoolscience.com/scope.htm

if ur talking about cells... i think it is organelles...not sure
