Programmed cell death in plant development
... Plants live very economically. When the cell wall itself is able to accomplish a specific function, the protoplast is eliminated. Sclerenchyma cells are dead because thick cell walls perform the mechanical function. Phellem, commonly known as cork, is constituted of characteristic cells with a thick ...
