04-006h 04-006h Wall between older (right) and younger (left) vessel members. Microtubules accumulate near the secondary wall in younger cell. Membrane-bound vesicles appear as blebs on plasmalemma. Primary wall of older cell are partly hydrolyzed. copyright: Katherine Esau and Jennifer Thorsch, BSA
