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.
Large tracts of cells with a similar structure that form a collective function are referred to as tissues. Complex organs such as flowers, leaves, stems, roots and fruits are all made up of various types of tissues. There are two basic types of tissues: 1  Meristematic tissue is found in the roots and shoots of plants.esson Structure.
