What is environmental stress? Describe two major environmental stresses in plants?

Environmental stress refers to the adverse conditions or factors in an environment that negatively impact the growth, development, and overall health of plants. These stress factors can be either natural or man-made and often disrupt the physiological and biochemical processes of plants, leading to reduced productivity or even death. Environmental stress can be categorized into two types: abiotic and biotic. Abiotic stresses, which are non-living factors, include factors such as extreme temperatures, drought, flooding, soil salinity, and pollutants. Biotic stresses, on the other hand, are caused by living organisms such as pests, pathogens, and weeds. Among these, two of the most significant abiotic environmental stresses are drought and high temperatures.
