Summary[edit]

Description
English: Growing plant cells produce a primary cell wall around themselves. Some cells add a sturdy secondary cell wall to protect themselves against pathogens and drought. The strength of the secondary cell wall is primarily provided by lignin (and the size of the wall). The plant cell, with a vacuole in blue, is shown in the middle.
Italiano: Le cellule vegetali in divisione e accrescimento producono una parete cellullare primaria intorno a sé. L'85-90% della parete primaria è costituita da una componente glicoproteica, mentre la rimanente è componente fibrillare, costituita da microfibrille di cellulosa. Alcune cellule costruiscono una robusta parete cellulare secondaria per proteggersi contro gli agenti patogeni e la siccità. La forza della parete secondaria è principalmente dovuta alla presenza di sostanze accessorie (che determinano le modificazioni della parete) come la lignina, e dalle sue dimensioni. La cellula vegetale, con un vacuolo in blu, è mostrata al centro.
