Abscisic acid (ABA) is called the stress hormone in plants because it helps them survive under stressful conditions like drought 🌵 or cold. When the plant senses stress, ABA signals the stomata (tiny pores on leaves) to close, reducing water loss.
✅ ABA protects plants during stress by conserving water and slowing down growth.
