A plant may close and open its stomata to prevent excess water loss and maintain homeostasis.
Homeostasis is termed as the tendency of organisms to maintain and automatic regulation of their internal environment to be in a stable condition.

The natural resistance which changes the optimal condition brings about homeostasis.
