Which of the following is an adaptation of weeds for survival?

Deep taproots are a significant adaptation for weeds that enhance their survival, particularly in challenging environmental conditions. These deep roots allow plants to access moisture and nutrients that are unavailable to those with shallower root systems, especially during periods of drought or in nutrient-poor soils. The ability to tap into deeper soil layers gives weeds a competitive advantage over other plants, enabling them to thrive in various habitats.

Furthermore, deep taproots can also anchor the plant securely in place, making it difficult for disturbances, such as heavy rains or winds, to dislodge them. This resilience contributes to their ability to colonize disturbed areas quickly, ultimately ensuring their survival and propagation. In contrast, adaptations like thin stems, high water consumption, or slow growth rates do not provide the same competitive edge that deep taproots do, making them less effective strategies for survival in the diverse environments where weeds are often found.
