ABSTRACT
The article investigates the anatomy and physiology of a rose focusing on the phloem. The rose has two types of phloem including the primary phloem producing terminal meristems at the tips of shoots and the secondary phloem being generated by the cambium. Rose canes are producing less phloem than xylem cells. The phloem contains 4 cell types including the sieve tubes, fibers, companion cells and parenchyma. Phloem transport could be driven by diffusion pressure flow and electroosmosis.

    The article presents information on cambium, the tissue or sheath of cells that surround the entire rose cane. It explains why the cambium is known as a meristematic tissue. Since the cambium runs up and down the stem, it is called a lateral meristem. Additive growth and multiplicative growth...

    A definition of the term "meristem" is presented. It refers to plant tissue whose cells actively divide to produce new tissues that cause the plant to grow. The cells of the meristem are not specialized but can become specialized to form the tissues of roots, leaves and other plant parts. The...

    Cambial injury has been reported to alter wood structure in broad-leaved trees. However, the duration and extension of associated anatomical changes have rarely been analysed thoroughly. A total of 18 young European ash (Fraxinus excelsior L.) trees injured on the stem by a spring flood were...
