Do plants scream when damaged?
A study of tomato and tobacco plants suggests they emit ultrasonic popping sounds when dehydrated or physically damaged. When deprived of water or snipped with scissors, plants emit a flurry of staccato screams that are too high-frequency for humans to hear, a study suggests. Tomato and tobacco plants make distinctive sounds when cut or dehydrated, a new study has found. Those sounds change depending on the plant emitting them and the type and severity of the threat that prompts them, according to the study in Cell.
Can plants hear you?
Research has shown that plants can respond to human voices and exhibit effects on their own. This has been studied since 1800 and has shown positive effects of talking to plants on their growth. The Royal Horticultural Society studied this fact by using tomato plants. While plants don’t see like humans, they can detect changes in light, colors, and their surroundings, which influences how they grow and respond to the environment.
