Plants can respond to the any change in the surrounding environment and adapt themselves by modifying their morphological, anatomical, physiological or behavioural changes. But they may not feel like animals because they didn’t have any nervous tissue or brain.
If plant are able to respond to stimuli then they can also respond to the feel. Anything that does not respond to stimuli does not respond to touch and anything that respond to touch also feel. So plant also feel
Yes, very much plants feel the touch. Most of the plant species may not show phenotypic expression/modifications unlike plant called Mimosa pudica (touch me not plant). it is very well proved that plants grow very well even for music sound. when insect bites plants, they generally express genes involved in both antibiosis and antixenosis resistance mechanism. Antibiosis, which reduces insect feeding, growth rate, or survival. Antixenosis,which affects insect settling, colonization, or oviposition
