Answer 1

The series of invisible and visible responses of plant cells and tissues to pathogenic organisms or environmental factors that result in adverse changes is referred to as plant stress responses or plant defense responses. More specifically, when these responses lead to evident changes in the plant's morphology or physiology, they may also fall under the category of plant pathology or plant disease responses. These responses can include a variety of mechanisms such as hypersensitive response (HR), systemic acquired resistance (SAR), or other forms of resistance and adaptation, depending on the type of stress or pathogen involved.
