The Stress Signal: Abscisic Acid Function

This quiz contains 20 questions about the function of abscisic acid, a crucial plant hormone involved in stress responses. You will explore concepts like drought tolerance, seed dormancy, and the regulation of stomatal closure....

Questions: 20 | Attempts: 19 | Last updated: Mar 9, 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
