Tropism theory

Tropism theory describes how plants grow or bend toward certain stimuli, such as light, gravity, or moisture. This movement is a natural response that helps plants optimize their chances of survival and growth. For example, sunlight causes plants to grow toward the light source (positive phototropism), while gravity influences roots to grow downward (positive geotropism). These responses result from the plant's cells reacting to specific environmental cues, directing growth accordingly. Tropism is essential for a plant's ability to orient itself, find resources, and thrive in its environment.
