Water.
you're welcome GradPoint :)
Hydrotropism is observed when specific plants that exhibit it grow in response to water, similar to Gravitropism, growth dependent on gravity, and phototropism, growth dependent on light. A common example of hydrotropism is found in tomato roots, as they grow specifically towards water.
Roots show positive hydrotropism and grow in the direction of water. This tropism causes problems in many cities where tree roots grow toward the drain pipes, and grow into the cracks, and plug up the drains. Hydrotropism causes plants to bend or turn toward water.
Tropism is the easiest plant behavior to recognize; it means growing in a particular direction. Phototropic plants, for example, grow toward the sun. Plants also send their roots down or sideways based on the climate, in order to find water (hydrotropism).
a "tropism"; geotropism for response to gravity and phototropism for response to light
No penuts do not grow on plants,they grow in the ground
hydrotropism is the positive response that plant roots give when there is water or a moisture gradient nearby, which means they growth towards the water

Hydrotropism
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a biology teacher. this is bullcrap it is fake
Tropism
This can be shown as some pea seedling reverse their geotropic response and grow upward to damp vermiculite(moist saw dust) this shows hydrotropism is stronger than geotropism

An organism exhibits positive or negative hydrotropism if it tends to move toward or away from moisture.
Response is a characteristic of all living organisms. One example of plants responding can be seen with their response to light- a plant will grow towards a light source.
It seems there might be a slight confusion in your question. If you meant "tropic response," it's likely that you are referring to "tropism." Tropism is a biological phenomenon where an organism, or a part of an organism, responds to an external stimulus by moving or growing in a particular direction. Tropisms are often observed in plants. There are different types of tropisms, including: Phototropism: The response to light. For example, plants often bend towards a light source as a way of maximizing their exposure to sunlight for photosynthesis. Geotropism (Gravitropism): The response to gravity. Plant roots typically grow in the direction of gravity (downward), while stems and leaves grow against it (upward). Thigmotropism: The response to touch or physical contact. This can be seen in the way some plants grow or coil in response to touch or nearby objects. Hydrotropism: The response to water. Plant roots may grow towards a water source, allowing the plant to access essential moisture. Tropisms are essential adaptive mechanisms that help organisms interact with their environment and optimize their chances of survival. While tropic responses are more commonly associated with plants, certain directional responses to stimuli can also be observed in other organisms.
