What are 5 adaptations of the Salix arctica (Arctic willow)?
I already have that they form a pesticide to keep insects away, a shallow root system, and fuzzy hairs on leaves. If you could list two more it'd be a huge help! :)
Salix arctica or Arctic willow prefers cold, dry climates and therefore the tundra is a perfect place for it to grow. Adaptations for survival include the following-- this plant can manufacture its own pesticides to protect it from insect pests. It has a shallow root system. This is advantageous as the amount of rainfall in this area is only 6-14 inches per year. By having a shallow root system, the plant absorbs the rain into these shallow roots which are close to the surface. If the roots were deep down, the rain might not permeate that far below the surface and the plant would die. Also, because there is permafrost, the roots wouldn't be able to penetrate below the surface soil to any great depths. The plant is adapted to the cold weather by growing long fuzzy hairs. The willow grows close to the ground. This adaptation is for protection from the wind. Therefore, these plants are found well above the treeline in harsh environments. The plant grows like a carpet on the ground. This adaptation allows it to gain heat energy from the soil. Since this species has separate female and male plants, since the two sexes grow in proximity to eachother, this aids in their sexual reproduction success rate to form seeds. Also, sometimes, the stems can form roots which touch the ground and can grow into new plants. This plant is very adapted to its harsh, cold and dry Arctic environment.
