Other Than the Presence of Water,______ Triggers Germination in Cool-Climate

Question

Other than the presence of water,______ triggers germination in cool-climate plants.  
A) bright light
B) exposure to freezing temperatures
C) abrasion of seed coat
D) presence of smoke
E) burning

Accepted Answer

Exposure to freezing temperatures triggers germination in cool-climate plants through a process called stratification, which breaks down the seed coat and initiates growth. Bright light, abrasion of seed coat, presence of smoke, and burning are all factors that may also play a role in germination of certain plants, but they are not specifically related to cool-climate plants.
