It depends on the type of fiber.
A contrast or optical microscope.
Transmission electron microscope.
compound
We used a microscope to observe the organism.
A scientist would use a light microscope to determine the size and shape of a cell. A light microscope uses visible light to illuminate the object being viewed. Light microscopy is used to observe the overall size and shape of a cell. An electron microscope is used to observe the structure and contents of a cell, including membrane-bound organelles.
