Web6 okt. 2024 · The de novo cell wall is initiated by a conserved land–plant specific structure called the phragmoplast during division (Jürgens, 2005; Buschmann and Zachgo, 2016). The main purpose of the phragmoplast is to generate a new cell wall after separation of duplicated DNA during cytokinesis (Smertenko et al., 2024; Lee and Liu, 2024). WebLet us see if all cell walls are made of cellulose. Not all cell walls are made of cellulose. The cell wall accounts for the majority of the plant’s dry weight and is made up mostly of three polymer components in which dry plant has 40 to 50% cellulose, 15 to 25% hemicelluloses, 20 to 25% lignin, and 5 to 10% additional components.
