Examples of stimulus reaction in plants include phototropism (response to light), gravitropism (response to gravity), thigmotropism (response to touch), and hydrotropism (response to water). These responses allow plants to adapt to their environment and optimize their growth and survival.
Water. you're welcome GradPoint :)
Hydrotropism is a plant's growth response to water. Plants will grow towards sources of water to ensure they have enough for survival and growth. This response helps plants adapt to changing environmental conditions.
Plants showing hydrotropism grow in response to water gradients in the soil. They sense the direction of water availability and direct their root growth towards the source of water to optimize water uptake for survival and growth.
The different types of tropic movements in plants are phototropism (response to light), geotropism (response to gravity), thigmotropism (response to touch), hydrotropism (response to water), and chemotropism (response to chemicals). These movements help plants adapt to their environment and optimize their growth and survival.
Phototropism: the growth of plants in response to light, such as bending towards a light source. Geotropism (gravitropism): the growth of plants in response to gravity, such as roots growing downward and stems growing upward. Thigmotropism: the growth response of plants to touch or mechanical stimuli, such as vines coiling around a support. Hydrotropism: the growth response of plants in search of water, where roots grow towards a water source.
Tropisms are plant's response to a particular stimulas. Tropisms demostrate that plants can response to light, water, gravity and chemicals. We, humans know what we want and with our knowledge we seek for it. Unlike humans, plants doesn't know what they want and how to look for it. So plants response to stimulus in order to get what they want and to survive. Plants turn towards light in order to make food. Tropisms helps plants to survive as plants cannot move and has no knowledge.
In this experiment, the dependent variable is the height of the bean plants. This is because the height is what you measure in response to changes in the independent variable, which is the amount of water the plants receive. As the amount of water varies, you observe how it affects the growth and height of the plants.
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.
Tropism is the response plants have towards external stimulus.
