Huckleberry shoot, light micrograph. Longitudinal section through the top of a terminal shoot from a huckleberry (Gaylussacia baccata). The pale pink cells at bottom are stem cells that are undergoing elongation and vacuolisation (becoming filled with vacuoles, which are fluid-filled cavities). The smaller and darker pink apical meristem cells towards the top are undergoing mitosis and have fewer vacuoles but denser cytoplasm. Surrounding the apical meristem and stem cells are leaf primordia (young leaves). Magnification: x100 when printed 10 centimetres high.
