Unformatted text preview: The corpus meristem cells under the tunica divide in a plane that adds bulk to the shoot meristem. Generally there are two tunica layers and one corpus layer. As a shoot grows, buds are laid down by shoot meristem in the axils of leaf primordia. The repeating units of leaf and bud primordia are called phytomeres. These buds are dormant meristems that are activated at some later time in growth. Stem tissues are produced from the same three derivative meristems as root tissues are: Protoderm is responsible for Epidermis Ground Meristem differentiates into ground tissues Procambium produces the vascular tissues Coleus stem tip, l.s. Shoot tip, xs SEM of shoot tip...
