What stresses a plant?
Two types of environmental stresses are encountered to plants which can be categorized as (1) Abiotic stress and (2) Biotic stress. The abiotic stress causes the loss of major crop plants worldwide and includes radiation, salinity, floods, drought, extremes in temperature, heavy metals, etc.
How do you tell if a plant is stressed?
A common sign your plant is stressed is if it’s dropping leaves and flowers. Stressors can include lack of water, over watering, temperature change, less light – you name it. If the problem isn’t too little or too much water, or something else easy to identify, have patience.

How do plants respond to hormones?

Which plant structure is most involved in photosynthesis?
