Practice question

Go with B — Ψsoil > Ψroot > Ψstem > Ψleaf > Ψatmosphere. Under WATER POTENTIAL, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Ψleaf > Ψroot > Ψsoil; C) Ψroot > Ψsoil > Ψleaf; D) Ψatmosphere > Ψleaf > Ψroot. When two options sound similar, choose the one that matches the textbook definition most tightly.
