BRAINCAKEPlant Defences against Pathogens
Receptors inside plant cells bind to molecules produced by pathogens or molecules produced when the cell wall is damaged.
This activates signalling molecules that switch on genes that cause cellular responses to the pathogens.
These responses include producing defensive chemicals, sending alarm signals to other cells and strengthening the cell walls.
