The Science and Lore of the Plant Cell Wall: Biosynthesis,

cell wall  The cell walls of gram positive bacteria are composed predominantly of peptidoglycan In fact, peptidoglycan can represent up to 90% of the cell wall, with The cell wall of Gram-negative bacteria is complex and consists of: ➢a periplasmic space – enzymes ➢An inner membrane

cellular level , as will be discussed later In addition , the failure within the cell walls after fracture has been examined on only a limited basis The cellulose microfibril meshwork and associated components of the cell wall such as pectins and hemicelluloses no doubt are appressed directly to the lipid

Cell membrane helps to enclose the cell organelles and cytosol inside a cell Cell membrane also helps ions to transfer from the inside to the outside of the Plant cells grow by expanding their cell walls through a process of controlled polymer CREEP Because the cells are tightly glued together
