ANSWER: The presence of cork cambium depicts that the plant has undergone secondary growth.
EXPLANATION: Cork cambium is also referred to as is also known as Phellogen (a meristematic cell layer). It is found in vascular plants and located in the peridermis.
However, presence of cork cambium indicates that the plant has undergone secondary growth, which is elicited as a result of cell division in the cambia or lateral meristems, which in turn causes the stem and root to thicken.

Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.
