Question

when a plant is said to be dead???

Answer 1

If both the stems and roots are brittle or mushy, the plant is dead.

Answer 2

There has always been a strong interest in how adverse environmental conditions, particularly water deficit, affect plant health and mortality. In recent years research has been expanded to include the phenomenon of climate extremes (Pfaustch and Adams 2012) where heatwaves, compounded by lengthy droughts, can have a significant effect on plants. Modelling and predicting the physiology of plant mortality is critical in the management of crops and forests. However, scientists currently face an intriguing problem – at the moment there is no definition, or consensus, for when a plant is actually dead!
