In vascular plants, which substance is primarily transported upward through the xylem?
A
Sucrose and other organic nutrients
B
Water and dissolved mineral ions
C
Proteins synthesized in leaf mesophyll cells
D
Oxygen produced during photosynthesis
Verified step by step guidance1
Understand the function of xylem in vascular plants: Xylem is a type of vascular tissue responsible for transporting substances within the plant.
Recall that xylem primarily transports water and dissolved mineral ions absorbed from the soil, moving them upward from the roots to the leaves.
Recognize that sucrose and other organic nutrients are transported by phloem, not xylem.
Note that proteins synthesized in leaf mesophyll cells are generally used within the plant cells and are not transported through xylem.
Understand that oxygen produced during photosynthesis is typically released into the atmosphere and not transported through xylem.
