What can excessive water loss through transpiration lead to in plants?

Excessive water loss through transpiration in plants can lead to wilting, which is a physical condition characterized by drooping leaves and stems. Transpiration is the process where water evaporates from the surface of leaves, creating a pull that helps transport nutrients and water from the roots through the plant. However, if a plant loses too much water, it can result in insufficient water supply for essential processes like cell turgidity, supporting the structure of leaves and stems. When turgor pressure decreases due to lack of water, leaves may droop or wilt as the plant struggles to maintain its structure and function. Wilting is a sign that the plant is stressed and may not be receiving adequate hydration to support its growth and metabolic activities.
