|
What creates the transpiration pull that helps water move up through the xylem?
cohesion of water molecules
adhesion of water molecules to xylem vessel walls
evaporation of water at leaves
absorption of water by root hair cells
|
Which of the following statements about the apoplast pathway is true?
water moves through plasmodesmata
water movement is helped by the Casparian strip
water moves through the cytoplasm of cells
water moves through spaces in the cell walls and between cells
|
Which of the following statements about the symplast pathway is true?
water movement is blocked by the Casparian strip
water moves from cell to cell through the cytoplasm and plasmodesmata
water moves through the xylem vessels
water moves through spaces in the cell walls and between cells
|
What is the role of stomata in the water movement process in plants?
to facilitate the movement of water through the phloem
to allow water to enter the plant through the roots
to prevent water loss from the plant
to allow water to evaporate from the leaves
|
Which of the following best describes the movement of water through a plant?
water enters the leaves, moves through the phloem, and exits through the roots
water enters the roots, moves through the phloem, and exits through the leaves
water enters the leaves, moves through the xylem, and exits through the roots
water enters the roots, moves through the xylem, and exits through the leaves
