Thigmotropism simple definition
Web27 Dec 2024 · The key difference between thigmotropism and thigmonasty is that thigmotropism is a directional response of a plant organ to touch or physically contact a solid object. Meanwhile, thigmonasty is a form of non-directional movement by a plant in response to touch or vibration. Living organisms respond to different internal and external … WebPhototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.

In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.
