Following are the list of some of the molecular “danger signals” (column I) and its characteristics (column II)
Column I Column II
a) MAMPs i) produce from the pathogen molecules support their ability to successfully colonize their host and gain nutritional benefits
b) DAMPs ii) A plant response to insect herbivores involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant
c) Effectors iii) are conserved among a specific class of microorganisms such as chitin for fungi, flagella for bacteria
d) Elicitor iv) molecules secrete from the damaging plant by herbivory such as Prosystemin
Which of the following is the correct match between the signals and their respective mechanism?

When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate into individual sodium ions (Na+) and chloride ions (Cl-). In contrast, the atoms of covalently bonded molecules (e.g., glucose, sucrose, glycerol) do not generally dissociate when placed in aqueous solution. Which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions)?

Due to damage exudation of sap from cut petioles or stems takes place they can be collected. However, quantities of collected sap are small, and the method is technically difficult. A preferable approach for collecting exuded sap is to use an
