Different Shapes and Sizes of Cells


Each different cell has a different shape according to its function. Its size is also a major factor in what the cell's function is.


Nerve Cell:

  • The long extensions of the nerve cell help it to transmit impulses all throughout the body.

    Plant Cell:
  • The cell wall of a plant cell helps to protect the cell, it provides support and shape, and it helps it to fit together with other plant cells.


    These onion cells fit together perfectly, and they are well protected.


    Sperm Cell:
  • A sperm cell has a long flagellum that helps it to make its way to the egg cell. It is also very tiny.


    This diagram shows the parts of a sperm cell. Notice its long flagellum.



    Blood Cells:
  • The tiny shape of a blood cell allows it to fit through the blood vessels, which have a very small diameter.


    These blood cells are tiny enough that they can fit through the blood vessels in bunches.



    Muscle Cells:
  • The unique shape of muscle cells allows them to contract and expand, making the muscle move.
