Defense Compounds

100

Which of the following is a mobile signal molecule in SAR? (traveling to distal tissues) 

a) WRKY

b) NPR1

c) Pip

d)MeSA

MeSA

200

Transgenerational (SAR passes onto offspring) SAR is caused by:

a) Activation of Bax

b)Transcription of p53

c) Histone tail modifications

d)SA accumulation in seeds

Histone tail modifications

300

What is the role of Pip?

The role of Pip is to form early SAR signaling by inducing the collection of salicylic acid. 

400

What is an example of indirect defense?

Plants release volatile compounds into the air that attract predators, which in turn harm the herbivores attempting to damage the plants. 

500

Correct order of Steps for SAR

Pathogen attacks 

Pip Accumulates

SA is converted to MeSA

MeSA travels to distal tiddues and is converted back to SA

Receptors are activated 

WRKY initiates transcription

Drupe

200

1 seed with a thin pericarp, the seed used to pericarp, such as corn or wheat

Caryopsis/grains

300

1 carpel, two structures such as beans and peas

100

What are Meristems? 

a) Vascular tissues that supply the plant with nutrients 

b) Tendrils that originate from stems

d) Areas of cell division and growth

Areas of cell division and growth

200

What is the main difference between a complete flower and a perfect flower?

A complete flower has all four whorls, while a perfect flower has carpels and stamens (the male and female reproductive organs) 

300

What is the main difference between a tap root and fibrous roots

A tap root is a single primary root that is usually deep in the soil, while fibrous roots are near the soil surface and have many secondary roots. 

400
