How do plants respond to touch stimuli and what mechanisms are involved in their tactile responses?
Plants respond to touch stimuli through a process called thigmotropism, where they change their growth direction in response to touch. This is controlled by hormones like auxin and ethylene, which help regulate cell growth and movement in response to touch. Additionally, plants have specialized cells called mechanoreceptors that detect touch and trigger a cascade of signaling pathways to initiate a response.
What is stimulus in plants?
In plants, a stimulus is a signal from the environment that triggers a response in the plant. This can include factors like light, temperature, touch, or chemicals. Plants use these stimuli to adapt and respond to changes in their surroundings to maximize their chances of survival and growth.
How Do Plants respond to stimuli Give examples?
Plants respond to stimuli through growth movements. For example, phototropism is their response to light, causing them to grow towards it. Thigmotropism is their response to touch, triggering growth in response to physical contact. These responses help plants adapt and survive in their environment.
Do carrots respond to stimuli?
Carrots do not respond to stimuli in the same way that animals or some plants do. They lack a nervous system and do not have the ability to perceive or react to external stimuli like light or touch. Carrots do respond to environmental conditions such as sunlight, soil nutrients, and water availability by growing roots and leaves accordingly.
Which plants are known to exhibit thigmotropism, a response to touch or contact stimuli?
Plants such as vines, tendrils, and some climbing plants are known to exhibit thigmotropism, a response to touch or contact stimuli.
How does plants respond to touch?
Some plants dont like it when you touch them they need to be nurtured carefully
How do flowering plants respond to stimuli?
through closing their leaves or flowers like "touch me not plant"
Name three stimuli to which plants respond?
gravity light and touch are the three stimuli for plant tropisms.

What is the primary distinction between plants and animals?
Plants DO NOT respond to stimuli
Nerve endings that respond to temperature and touch?
Thermoreceptors respond to temperature changes, detecting both hot and cold stimuli. Mechanoreceptors respond to mechanical stimuli such as touch, pressure, and vibration.
Which plants are known to exhibit thigmotropism, a response to touch or contact stimuli?
Plants such as vines, tendrils, and some climbing plants are known to exhibit thigmotropism, a response to touch or contact stimuli.
What are three examples of the stimuli to which the skin can respond?
Three examples of stimuli that skin can respond to are temperature changes (hot or cold), touch or pressure, and exposure to chemicals or irritants.
Which Indian scientist discovered that plants respond to external stimulus?
Indian scientist Sir Jagadish Chandra Bose conducted pioneering research that demonstrated that plants respond to external stimuli. He observed and recorded plant responses to various stimuli such as light, sound, and touch, laying the foundation for the field of plant physiology.
