Woody plants produce wood as their structural tissue. Cross sections of woody stem plants often make some of the most beautiful microscope slides, as they are filled with color.
This image is a cross section of a woody stem captured under the Zeiss Primostar HD digital microscope at 40x magnification.
Wood is primarily composed of xylem cells with cell walls made of cellulose and lignin. Xylem is a vascular tissue that moves water and nutrients from the roots to the leaves, and is one of the reasons viewing cross sections under the microscope are so magnificent, because the cell structure is visible.
