薄壁组织 Parenchyma Tissue • Parenchyma cells usually have only thin primary walls; typically alive at maturity. • Functions include: basic metabolism, photosynthesis, storage etc. For example, Aerenchyma (通气组织), Chlorenchyma (绿色组织)
Figure 4.2 Parenchyma cells. They are more or less spheri- cal when first formed, but as their walls touch other parenchyma cell walls, the cells end up with an average of 14 sides at maturity, x100.(Photomicrograph by G S Ellmore)
