Following are given some prediction about stress response which ultimately generate ROS;

a) Stress response activates the scavenging mechanism by ROS , these ROS is responsible for activating self-generation  mechanism by using RBOH

b) ROS have a negative effect on plant growth,  development,  and  yield

c) Almost every stress leads to the activation of ROS and its signal transduction

d) ROS indirectly induce acclimation mechanisms
