1: What material(s) is/are transported by the cells within the red oval?

Secondary growth in stems involves two meristems.  Identify and describe these two meristems, explain what tissues they are responsible for producing (including their functions), and explain the direction of cell division in which those tissues are produced in relation to the epidermis.  For the last part of this question referring to the direction of cell division, make sure to address why cell division is occurring in two different planes.  Also, as part of your answer, name and explain the functions of the tissues from the center of the stem to the dermal layer, in order, for a stem conducting secondary growth.
