How do plants adapt to stress and what are some examples?

Answer 1

Yes, even though they never have to write term papers or worry about paying their bills on time, plants can be stressed. They're widely known to change their color, smell, or shape in response to stress, and recent research (though not yet peer-reviewed) suggests that they even let out their own kind of "screams" in the face of it. Relatable.

Conditions that can put a plant under pressure include drought, snipped stems, disease, excess levels of salt, and uncomfortable weather conditions. To capture their ultrasonic screeches, researchers out of Tel Aviv University put microphones up to stressed tomato and tobacco plants. The researchers suggest that the squeals are a result of air bubbles popping within the plants, and although they're too high pitched for humans to hear, they think insects might be able to hear them.

Answer 2

Plant pressure is where a plant is developing in non-perfect development conditions and has expanded requests put on it. Plant pressure alludes to any negative condition or substance that influences a plant's digestion, generation, root advancement, or development. Plant pressure can come in various structures and terms.

Answer 3

Plants adapt to stress by changing their physiology and morphology. For example, they may close stomata to reduce water loss during drought, synthesize protective compounds against herbivores, or develop deep roots to access water in dry conditions. Other adaptations include increasing antioxidant production to combat oxidative stress, altering flowering times in response to temperature changes, or shedding leaves to conserve energy during stressful periods.

Answer 4

Both plants and animals respond to stress by using adaptations that help them evade, tolerate, or recover from stress. In a synthetic paper A. D. Bradshaw (1972) noted that basic biological differences between plants and animals will have diverse evolutionary consequences, including those influencing how they deal with stress. For instance, Bradshaw argued that animals, because they have relatively well-developed sensory and locomotor capacities, can often use behavior and movement to evade or ameliorate environmental stresses. In contrast, he predicted that plants will have to emphasize increased physiological tolerance or phenotypic plasticity, and also that plants should suffer stronger selection and show more marked differentiation along environmental gradients. Here we briefly review the importance of behavior in mitigating stress, the behavioral capacities of animals and plants, and examples of plant responses that

are functionally similar to behaviors of animals. Next, we try to test some of Bradshaw's predictions. Unfortunately, critical data often proved non-comparable: plant and animal biologists often study different stressors (e.g., water versus heat) and measure different traits (photosynthesis versus locomotion). Nevertheless, we were able to test some of Bradshaw's predictions and some related ones of our own. As Bradshaw predicted, the phenology of plants is more responsive to climate shifts than is that of animals and the microdistributions of non-mobile, intertidal invertebrates (''plant'' equivalents) are more sensitive to temperature than are those of mobile invertebrates. However, mortality selection is actually weaker for plants than for animals. We hope that our review not only redraws attention to some fascinating issues Bradshaw raised, but also encourages additional tests of his predictions. Such tests should be informative.

Answer 5

Plant stress is a state where a plant is growing in non-ideal growth conditions and has increased demands put on it. Plant stress refers to any unfavorable condition or substance that affects a plant's metabolism, reproduction, root development, or growth. Plant stress can come in different forms and durations.
