A nucleus is generally 10 to 20 micrometers in diameter. However, in humans, nuclei are only 6 micrometers in diameter on average. Mitochondria are approximately 1 micrometer in length. Chloroplasts can be up to 10 micrometers long and 0.5 to 2 micrometers thick. However, they do vary in shape and size in different types of cells The nucleus is the largest cellular organelle in animals. In mammalian cells, the average diameter of the nucleus is about 6 micrometers (μm), which is about 10% of the total cell volume. The viscous liquid within it is called nucleoplasm, and is similar in composition to the cytosol found outside the nucleus Although the nucleus occupies around 10% of the volume of a mammalian cell, it is still only approximately 6µm, or 6 thousandths of a millimetre, in diameter. The human genome, however, is over two metres in length. For a long time, its ability to fit inside the cell seemed miraculous The nucleus is the largest cellular organelle, and the only one visible using a light microscope. Much like the cytoplasm of a cell is enclosed by a plasma membrane, the nucleus is surrounded by a nuclear envelope that separates the contents of the nucleus from the contents of the cytoplasm How to Calculate Angular Size of DSOs?

The nuclear lamina might also play a role in the internal organization of the nucleus. For example, within the nucleus, chromosomes are organized in chromosome territories: rather than being distributed throughout the nucleus, each chromosome appears to occupy a discrete region, or territory (for a review, see Cremer et al., 2006) For example, a nucleus is generally between 5 and 10 micrometers, and a mitochondria can range from 1 to 10 micrometers. A lysosome is around 2 micrometers. The endoplasmic reticulum is built in. The nucleus is one of the largest organelles in the cell, occupying about 10% of the cell's volume. In eukaryotes, the nucleus can also be clearly distinguished from the cytoplasm by a well-defined nuclear boundary. The nucleus is also typically attached to its fellow organelle, endoplasmic reticulum on one side

As you can see in the image, the shapes of the cells vary to some degree, so taking an average of three cells' dimensions, or even the results from the entire class, gives a more accurate determination of. are measured in micrometers (aka micron). The symbol for a micrometer is µm and it is equal to one millionth of a meter or one thousandth of a millimeter. Often it is not clear how the size of the cell is related to the size of the organelles. In this activity, you will explore the relationship of cell size t Mass of a large sensory neuron = 10-6 gram (from Groves and Rebec, Introduction to Biological Psychology, 3rd edition, Dubuque: Wm.C. Brown Publ., 1988) Number of synapses for a typical neuron = 1,000 to 10,000 Diameter of neuron = 4 micron (granule cell) to 100 micron (motor neuron in cord) Diameter of neuron nucleus = 3 to 18 micro
