No, no they do not. As well as not having a cortex, monocot stems don't have a pith either.
Vascular cambium is absent in monocot stems.

Vascular cambium is responsible for secondary growth in a stem.

monocot stems
In a monocot stem, vascular bundles are scattered throughout the stem. However, because the of the lack of vascular cambium, no secondary growth occurs in the monocot stem. As a result of increased cell size, the monocot stem will only increase in height only.
The monocots like the maize produce the cork cambium monocot.
the different internal structure of stem are epidermis, vascular bundles, cortex for monocot stems and to dicot, pith, vascular and cork cambium.
no there is no cambium present in monocot roots.
It's a woody stem
So sorry but you have that backwards. Bamboo which is a monocot is the fastest growing plant that there is. The reason for this is: monocots do not make as big an investment in their structural support, that is they do not grow as much wood as dicots.

monocot, with only the one stem of leaves.
vascular cambium
1. Number of cotyledones in the embryo of a seed 2. Absence of cambium in the vascular bundles 3. Scaterred vascular bundles in the stem. 4. Parallel leaf venation
