Consists of two other meristems: a)flank meristem-forms the cortex b)rib meristem-forms the pith-ground tissue has several functions, including storage, basic metabolism, and support. These functions are performed by its three kinds of cells: parenchyma, collenchyma, and sclerenchyma.onsists of two other meristems: a)flank meristem-forms the cortex b)rib meristem-forms the pith. -. has several functions, including storage, basic metabolism, and support.
