Adhesive pad of fungi penetrates the host with the help of : -
A
Mechanical pressure and enzymes
B
Hooks and suckers
C
Softening by enzymes
D
Only by mechanical pressure
Detailed Solution
Many parasitic fungi form an adhesive pad (appressorium) on the host surface.
From it, a fine infection peg pierces the host cuticle and cell wall. This uses both mechanical pressure (high turgor pressure in the appressorium) and enzymes (cutinases and cellulases that soften the wall).
So the adhesive pad penetrates the host with the help of mechanical pressure and enzymes.
