part of multidimensional cell growth plant-type cell wall modification plant-type cell wall modification involved in multidimensional cell growth biological_process The series of events that occur during cell growth that result in chemical or structural changes to existing cell walls of the type composed chiefly of cellulose and pectin. An example of this is found in Arabidopsis thaliana.
