Summary Introduction
To review:
The components of the vascular cambium and their roles in secondary growth in stems, including the development of bark, cork, and wood.
Introduction:
Vascular cambium is the secondary meristem or lateral meristem, responsible for the secondary growth of a plant, that is, increase in girth of a plant. Secondary growth occurs in

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.
