The Stress Signal: Abscisic Acid Function

When conditions turn harsh, plants do not panic. They respond with molecular precision, and abscisic acid function is at the center of that stress response system. ABA triggers stomatal closure to conserve water during drought,...

Questions: 20 | Attempts: 10 | Last updated: Mar 8, 2026

Sample Question 1
What is the primary role of Abscisic Acid (ABA) during a period of severe drought?

Stimulating stomatal closure to conserve water

Increasing the rate of photosynthesis

Promoting the growth of large leaves

Speeding up the flowering process

Encouraging the intake of CO2

Sample Question 2
In the context of abscisic acid function, it acts as the primary signal to maintain seed dormancy and prevent germination during winter.

True

False

Sample Question 3
Regarding abscisic acid function in molecular biology, which protein acts as the inhibitor that ABA must deactivate?

PP2C (Protein Phosphatase 2C)

SnRK2 (Protein Kinase)

PYR/PYL (Receptors)

DNA Polymerase

RuBisCO
