Final answer:
Wilting in plants can be caused by a lack of water. Water is essential for plants to maintain turgidity and support various physiological processes. Lack of water disrupts the plant's internal water balance and leads to wilting.
Step-by-step explanation:
Wilting in plants can be caused by a lack of water. When plants don't receive enough water, their cells lose turgidity, which is the internal pressure that keeps the plant upright. This results in the plant becoming limp and wilting.
A lack of water means that the plant's roots cannot absorb sufficient water to replace the water lost through transpiration. Transpiration is the process by which water evaporates from the leaves of the plant. When there is not enough water available for transpiration, the plant cannot maintain its internal water balance and wilts.
It's important for plants to receive adequate water to stay healthy and prevent wilting. Water provides plants with the necessary nutrients, supports photosynthesis, and helps transport nutrients and sugars throughout the plant.
