Endurance: The CD jewel case has a tight and firm grip of the CD because of the tray's teeth or lock. Because of this, even if the CD jewel case is turned upside-down, left, or right, the CD is held in place. Flimsier cases may cause the CD to become loose, or even fall out.
The growth tissues of the plants are meristems. Meristems are the tissues that produce plant growth, and are the origin of all other tissues. They are formed of undifferentiated cells with an intense cell division rate.5. The vascular cambium is the secondary meristematic tissue that forms the vascular tissues (xylem and phloem) of the plant in roots and in the stem. Usually, the outer side of the vascular cambium produces a layer of phloem and the inner (more central) side of the tissue produces a layer of xylem.
There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in vascular tissue are typically long and slender.Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.he cells in vascular tissue are typically long and slender.
