Question

When stomata are open and a plant is transpiring normally, how does water move from the soil into the root xylem? Select all that apply. a) driven by evaporation from the leaves b) driven by pressure generated by roots c) pumping water upward due to a tension that pulls the water upward without the plant doing any additional work on the fluid d) due to the action of ATP-driven pumps in the endodermis.

Answer 1

Answer:The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. To understand how these processes work, we must first understand the energetics of water potential.
