What is the process by which water travels along the cell wall during transpiration?
Can you explain to me the process by which water travels along the cell wall during transpiration?
Sure! During transpiration, water moves through the plant from the roots to the leaves. As it reaches the leaves, it evaporates from specialized structures called stomata. As the water evaporates, it creates a negative pressure or tension that pulls more water up through the plant's xylem tissue. The cell walls of the xylem are coated with a substance called lignin, which provides strength and support for the plant.
