For a mineral nutrient to get to the leaves, the mineral must make it to the plant xylem. Which layers would the
nutrient need to traverse in a dicot? What will be an ideal response?
ANSWER: The nutrient would enter the plant via the epidermis. Next, it would move through the
cortex. Following this it would cross the endodermis and pericycle. Finally, it would enter
the xylem.
