What is the initial visual change in a plant before it wilts from lack of water?

It will turn yellow
It will turn a darker blue-green
It will become spongy
It will develop brown spots

The correct answer is: It will turn a darker blue-green

The initial visual change in a plant due to lack of water often manifests as a darker blue-green color in the leaves, which is a result of the plant pushing water away from the leaf surfaces to conserve moisture. This phenomenon occurs before more severe symptoms, such as wilting, fully develop. In this stage, the chlorophyll concentration can become more pronounced, giving the leaves a richer color as the plant tries to maximize photosynthesis under adverse conditions. This adjustment is part of the plant's response to water stress, as it can temporarily modify its color and structure in an attempt to maintain its physiological functions. Over time, if the water deficiency continues, other symptoms, such as yellowing, sponginess, or brown spots may appear, indicating a more severe stress response.
