Tilia 3-Year Stem Prepared Microscope Slide

This prepared microscope slide presents a cross section of a three-year Tilia (basswood) stem, showing the characteristic growth ring structure that develops as the tree adds secondary xylem and phloem over successive growing seasons. Tilia is a genus of deciduous tree commonly used in plant anatomy studies because its stem structure clearly displays vascular cambium, annual rings, bark layers, and ray parenchyma. The slide supports biology classroom instruction on plant growth, secondary development, and structure-function connections aligned with NGSS standards. It measures 75mm (3") wide by 25mm (1") long and 0.06" in height. Expertly prepared and labeled for easy identification, with all materials completely inert and permanently sealed in glass. Arrives in a protective cardboard casing.
