In Class 10 Biology, 'Tropic movements' are directional growth responses of plants to external stimuli. 'Hydrotropism' is the specific phenomenon where plant roots grow in the direction of moisture (water). Here is a simple experiment to prove this.
In nature, hydrotropism is a survival mechanism. It allows desert plants and trees to send their roots deep and wide to find hidden underground water sources.
Roots show positive hydrotropism, but the plant stem (shoot) is completely unaffected by water direction.
Phototropism is a plant's growth response to light. Stems show positive phototropism (growing towards the sun), while roots show negative phototropism.
