The surface area of a plant's root system is substantially larger than the surface area of its shoot system. The extensive surface area of roots is an adaptation associated with .

Water and nutrient uptake.

Explanation:

The root system of a plant functions as conducting tissue for water and mineral nutrients that are essential for metabolic activities of the plant.

Extensive surface area of roots is an adaptation associated with efficient water and mineral nutrient uptake because this will increase the surface area of roots in contact with the soil.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
