Intussusception

 

the expansion of the cell wall in plants as a result of the introduction of new molecules of cellulose and protopectin into the already formed wall. Intussusception was previously contrasted to apposition, that is, the growth of the wall through the deposit of new layers from inside (from the protoplasm). Actually, both apposition and intussusception are observed during the growth and thickening of the cell wall.
