Question : What would you call the parenchyma cells that are mode to divide under controlled laboratory conditions during plant tissue culture ?

Answer»

Solution :Parenchyma cells that are made to divide to form callus under CONTROLLED laboratory conditions are example of DEDIFFERENTIATED tissue.
Growth in plants is open inspite of differentiation SHOWN by them.
It is so because cells/tissues that arising out of the single or same meristem show different structures after attaining maturity.
Thus the final STRUCTURE at maturity of a cell/tissue arising from the same tissue is also determined by the location of the cell e.g. cells positioned away from the root apical meristems differentiate as root-cap cells, while those which are pushed to the PERIPHERY develops and mature as epidermis.
