The behavior of chhui-mui (sensitive plant) and amla plants is primarily triggered by touch, a mechanical stimulus. When their leaves experience physical contact, they respond by folding inwards as a protective measure. This reaction serves multiple purposes, such as deterring herbivores by making the plant appear less appealing and conserving moisture during unfavorable conditions. Additionally, changes in light can also influence their leaf movements. Overall, these responses illustrate how plants can react to different stimuli in their environment for survival.
