The primary growth in vascular plants takes place with the differentiation of vascular tissue from parenchymatous cells and the secondary growth takes place when the intra-vascular and inter vascular cambium adds to the secondary phloem and secondary xylem.
Yes ! They are primary tissues as there is no secondary growth.
Meristematic tissue (vascular cambium) produces secondary growth. In plant stems, this serves to increase the diameter, and it forms between the primary xylem and phloem.

Secondary xylem
it's called the phloem. the tissue type is meristematic tissue.
Bark makes up the phloem tissue and a cork cambium that protects the stem.
muscle tissue
meristematic
secondary tissue are found tip of stem and tip of root
during secondary growth the primary epidermis spilt, dries, fall off. to protect the exposed tissues and to increase in diameter cork cambium aries in the cortex.
