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.
Marestematic TissueMaristematic tissue is composed of actively dividing cells. It is located on the growth point in stem tip. Cambium of dicotyledon, and root tip. Types of Meristematic Tissue Based on the location Meristematic tissue can be distinguished into apical, intercalary, and lateral meristems.Apical meristem is located on the tip of rood and stem. Intercalary meristem is located between mature tissues, e.g at the base of nodes in grass stem.asically, there are three types of primary meristem as follows. 1  Protoderm, which is the outer layer of developing tissues (derived from apical meristem). 2  Ground meristem, Which is meristem which form ground tissues. 3  Procambium, which is meristem which form vascular tissues.
