Vedclass · Answer

(A) An appressorium is a specialized hyphal structure that is used by some parasitic fungi to infect host plants. It adheres to the host surface and generates significant mechanical pressure. Simultaneously,the fungus secretes specific enzymes (such as cellulases and pectinases) to degrade the host cell wall. Therefore,the penetration is achieved through a combination of mechanical pressure and enzymatic action.
