Solution

Answer for question 5 on first page

all options are correct Beacause immune response in plant for specific pathogen mount through the all given way

A). Avirulance protein in pathogen does not cause any disease in plant.

B.) Chitin receptor are pattern recognition receptors found on the plasma membrane of plants.chitine does not found in plant,it is found in fungi.A fungal infection is leads to secretion of Chitin from the fungal cell wall which binds to receptors and start signalling to generate effective immune response against fungi.

C)Flagelline receptors are like Chitin receptors which recognise phytobacterial Flagelline protein and start signalling to elicit immune response.

D) Many disease resistance protein found in plant cytoplasm which detect disease causing bacterial ,viruss ,fungi by recognising specific pathogen effector molecules which are produced during infection.

Answer for the question 4 on second page-

Constitutive response: Because in first few months saplings of plants used resources to increase in height rather than producing defence molecules.

In constitutive response or defence include many protective barriers in plant such as cell wall, cuticle,bark,vaxy epidermis which protect plant from invading pathogen and plant can survive without producing defence molecules.

Constitutive defence also provide strength and rigidity.
