The leaf epidermis under light microscope view has small pores, called stomata, which open up for photosynthetic gas exchange and transpiration.
Pine Stem Cross Section seen on microscope at 200x Magnification. Phase Contrast Optical Microscope
Human hair in a scanning electron microscope
This is a microscopic image taken with an Olympus BX50 microscope of mouse quadriceps.  This particular cross section was stained with Hematoxylin which yields a blue to purple stain.  Each circular structure is an individual muscle fiber.
