Question

When a plant is attacked by a pathogen, what molecules are produced in response?

jasmonic acid

lignin

polysaccharides

phytoalexins

all of the above

Answer 1

Jasmonic acid - It induces various signaling pathway upon pathogen infection.

Lignin - Line human which have skin as the surface barrier for which prevent us from infection, plant have lignin over its surface which prevents it from pathogen infection,

polysaccharide - There are some studies that have shown that certain polysaccharides are produced upon infection in the plant cells.

Phytoalexins - They are the chemical compounds which are produced by plants during infection, Plants produce more than 15 types of phytoalexins. Chemically they are very diverse from each other.

So the answer is option E -all of the above
