Question
Chapter 37.2, Problem 1SB
Summary Introduction
To review:
The general and the specific chemical defenses of plants that are activated in response to a particular type of pathogen.
Introduction:
Unlike animals, the plants lack a proper immune system. However, they have evolved interesting mechanisms in order to combat the pathogenic attacks. Plants have the constitutive defense or barriers like bark, waxy coating, spines, hair, and chemicals that are produced in response to the pathogens. The bark and hair are similar to the animal skin. Secondary metabolites like alkaloids are produced in plants to kill the foreign bacterial cells.

(ii) (ii) Name the chemical compounds responsible in triggering SAR and how would this signal be transmitted?arrow_forwardChemical Defenses: What is the benefit of having an inducible chemical defense, as opposed to a constitutive chemical defense? (an inducible defense is when the chemical is produced when herbivory is taking place as opposed to a constitutive defense where the chemical is always present) Inducible chemical defense best deters herbivory. With inducible defense predation will take place before a defense compound is produced which means there is damage to the plant before a defense is employed. With inducible defense herbivores are deterred even if no defense compound is produced. With inducible defenses energy is conserved by only producing secondary compounds when needed instead of continually. b 9 A....pdf XE A Week 9 Pre-lab.pdf A 10.7591 978150 A AY9_Week9_ng....xlsxarrow_forward
