when meristematic tissues loose their capacity to divide the form permanent tissue
when these continuously dividing cells stop dividing and get their own jobs to do and become a permanent tissue, this process is called diferentiation
dedifferentiation, wehen PT regain their capacity to divide and help in secondary growth
redifferentiation, when PT again loose their capacity to divide
