Solution

The correct option is C Assertion is correct but Reason is incorrect.
A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant, where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing. The shoot apical meristem (SAM) gives rise to organs, like the leaves and flowers, while the root apical meristem (RAM) provides the meristematic cells for the future root growth.
Meristematic cells are living with highest mitotic activity in plants and lignin is a constituent of only dead plant cells. So, lignin is absent in them.
So, the correct answer is option C.
