What does a wilted leaf typically indicate in the context of plant health?

• A. Excess water
• B. Insufficient water
• C. Fungal infection
• D. Nutrient deficiency

Answer: (B)

A wilted leaf commonly indicates insufficient water within a plant. When a plant does not receive enough water, it is unable to maintain turgor pressure, which is the internal pressure that helps keep leaves and stems firm and upright. Without adequate moisture, plant cells lose their ability to remain turgid, leading to wilting and drooping leaves. This response is often the plant's way of coping with drought stress and can signal that the roots are not absorbing enough water, or that the overall supply is limited. While excessive watering can also lead to issues in plants, such as root rot, this condition typically presents differently than wilting. Fungal infections and nutrient deficiencies can lead to various symptoms, but wilted leaves are most accurately associated with a lack of water. Understanding this relationship helps in diagnosing plant health issues effectively.
