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.
meristem. (mÄr`istÄm') , a specialized section of plant tissue characterized by cell division and growth. Much of the mature plant's growth is provided by meristems. Apical meristems found at the tips of stems and roots increase the length of these sections.n one type of lateral meristem, called cambium, or vascular cambium, the cells divide and differentiate to form the conducting tissues of the plant, i.e., the wood wood,botanically, the xylem tissue that forms the bulk of the stem of a woody plant.
