What can happen to plants when soil moisture decreases?

Answer and explanation

Correct answer: Growth can decrease

The direct answer is A: growth can decrease. Soil moisture is the water available around plant roots. Plants use this water for photosynthesis, transport of minerals, cell expansion, and cooling through transpiration. Step by step: soil moisture falls; roots absorb less water; the plant may close leaf pores and reduce photosynthesis; cell growth and nutrient transport can slow; prolonged shortage may cause wilting, leaf loss, or death. Option A is correct because reduced water availability can reduce growth, although the exact effect depends on the plant and severity. B is wrong because water shortage does not always double growth. C is wrong because leaves do not turn into gold; yellowing may occur in stress but is not gold formation. D is wrong because roots cannot become sunlight. Memory cue: less soil water means more water stress and usually less growth.
