How do plants absorb water? Explain.
a. On the tip of the root, there are millions of that absorb water and minerals through diffusion.
b. Root hairs are , thin-walled outgrowth of the cell that enhances the absorption surface area.
c. Energy is used to pump molecules against a concentration gradient in transport.
d. The root hair cell wall is porous, allowing water and minerals to pass through. The membrane of the cell is .
e. As a result, water molecules can move from a concentration region to a low-concentration region.
f. The concentration of water molecules in the root hair cells exceeds that of after water penetrates the root hairs.
g. As a result, water from the root hair reaches the cortical cells via before reaching the xylem.
h. By the process of , water is lost from the leaves and pressure is created at the top to pull additional water from the xylem to the cells.
