Abiotic stress is defined as what?

Abiotic stress is defined as what?

• A. Non-living, adverse environmental stress such as frost or heat; not transmittable but can lead to biotic stress.
• B. Living pathogens causing disease.
• C. A type of insect feeding on leaves.
• D. Genetic resistance in plants.

Answer: (A)

Abiotic stress is stress caused by non-living environmental factors. These stresses are not contagious and don’t spread from plant to plant, unlike biotic stress which is caused by living organisms. However, severe abiotic stress can weaken a plant and make it more susceptible to diseases or pests, so it can lead to biotic stress. The other choices describe living pathogens, insect feeding, or a plant trait, none of which fit the definition of abiotic stress.
