Answer: These may be:
- physical defenses (1st line)
- chemical defenses (2nd line)
Explanation:
Plants employ several methods in order to defend themselves from pathogens. These may be physical defenses or chemical ones. Several have adaptations to their surfaces that prevent the entry of pathogens, called physical barriers such as
- thick waxy cuticles
- thorns, which are modified plant branches
- spines, which are modified plant leaves
- gall production at infected sites to prevent pathogenic spread
Chemical defenses include the production or secretion of:
- defensins
- antimicrobials such as tannins or resins
- gum at areas facing pathogenic attacks

The answer would be true
The objective of vaccination is to elicit the primary immune response by introducing pathogen antigens. This antigen can be a whole weakened pathogen or just part of pathogen proteins.
The antigen will activate the primary immune response cascade that <span>will </span>activate of B-cells and T-cells from the secondary immune response. This will makes secondary immune response ready when the real pathogen comes.
