Vascular Bundle. For platoweb users the answer is C.
the stems cells are called Blood Cells , Nerve Cells, cardiac cells and liver cells.
in xylem all the cells R dead IN PHLOEM EXCEPT PHLOEM FIBRES ALL R LIVING CELLS
i) Sieve tubes (ii) Companion cells (iii) Phloem parenchyma (iv) Phloem fibres
A layer of cambium cells separates the xylem and phloem tubes.
Height growth occurs in the apical meristem. Radial growth occurs at the cambium layer. Cells divide into phloem and xylem. Phloem cells become the bark. Xylem cells become wood. In the early season the cells are larger, as the season goes on and water, light, and nutrients diminish the cells become thicker walled and smaller. The different sizes are termed spring and summer wood and these are the rings that you can count to determine the trees age.

Yes, Phloem cells are alive.
Phloem cells are living vascular cells that carries sugar and organic substances throughout a plant.
the cells of phloem are the only ones with cytoplasm
in xylem all the cells R dead IN PHLOEM EXCEPT PHLOEM FIBRES ALL R LIVING CELLS
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
