A caterpillar consumes oak leaves, triggering a defense response. Which outcome occurs when methyl jasmonate signaling increases in the plant?

💡 Explanation

Increased methyl jasmonate triggers defense responses such as increased tannin production because this secondary metabolite deters herbivory. Therefore, tannin production increases, rather than nitrogen fixation, water transport, or photosynthesis, which are not direct defense mechanisms.
