What occurs to a vine during drought?

• A. Leaves flourish, and grapes ripen quickly
• B. Photosynthesis increases
• C. Vines suffer water stress, leading to wilting
• D. Vines thrive and grow aggressively

Answer: (C)

During a drought, a vine experiences water stress due to the lack of available moisture in the environment. This water deficit affects its physiological processes, leading to wilting. When a vine does not receive sufficient water, it is unable to maintain turgor pressure in its cells, which is essential for keeping the leaves and stems firm. As a result, leaves may droop or curl, and the overall health of the vine deteriorates. Additionally, drought conditions inhibit the vine's ability to carry out essential functions such as photosynthesis and nutrient uptake. While some plants might adapt and exhibit certain survival mechanisms, the primary response during a drought is increased stress, not flourishing or aggressive growth. This underscores the importance of adequate water supply for the overall health and productivity of vines.
