hydrogen bonding
ionic bonding
van der Waals forces
covalent bonding
|
Which of the following best describes the adhesion of water molecules in the xylem?
hydrogen bonding between polar water molecules and non-polar cellulose in xylem vessel walls
ionic bonding between water molecules and xylem vessel walls
covalent bonding between water molecules and cellulose
van der Waals forces between water molecules and cellulose
|
What creates the transpiration pull that helps water move up through the xylem?
absorption of water by root hair cells
cohesion of water molecules
adhesion of water molecules to xylem vessel walls
evaporation of water at leaves
|
Which of the following statements about the apoplast pathway is true?
water movement is helped by the Casparian strip
water moves through spaces in the cell walls and between cells
water moves through plasmodesmata
water moves through the cytoplasm of cells
|
Which of the following statements about the symplast pathway is true?
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
water movement is blocked by the Casparian strip
|
What is the role of stomata in the water movement process in plants?
to allow water to evaporate from the leaves
to prevent water loss from the plant
to allow water to enter the plant through the roots
to facilitate the movement of water through the phloem
|
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
|
Which of the following is not a property of water that contributes to its movement in plants?
cohesion
high specific heat capacity
polarity
adhesion
