A complex polysaccharide that provides flexibility to plant cell walls is: Glucose Pectin Starch Sucrose Roots branching from existing roots are called: Adventitious roots Taproots Meristem roots Parenchyma roots Plant stomata

The ______ is impermeable to passive water transport, and regulates what enters the xylem. Select one: a. meristem b. stomata c. palaside parenchyma d. guard cells e. casparian strip

Which of the following would require active transport? Select one: O a. Stomata opening b. Potassium moving through an ion channel O c. Water moving through aquaporins O d. Water diffusing into xylem from the root e. The tension in the leaf caused by evaporating water

The Casparian strip… I. is a waxy layer in the walls of the endodermal cells of the root II. promotes apoplastic movement of water and minerals across the endodermis III. provides an opportunity for regulation of mineral uptake by the plant
