mechanisms of plant response

Plants respond to their environment through various mechanisms that allow them to adapt and survive. These responses include growth changes, such as bending towards light (phototropism) and roots growing downwards in response to gravity (gravitropism). They also produce chemicals to defend against pests or stress, like releasing scents to attract beneficial insects. Additionally, plants can close their stomata to reduce water loss during dry periods. Through these mechanisms, plants effectively interact with their surroundings, optimizing their growth and protecting themselves from threats.
