16. Name and describe the three types of tissue systems in plants.
17. What materials move through the xylem?
18. The ______________ __________________ theory proposes that water can rise
through a plant due to (a)the tendency of hydrogen bonds to form between water
molecules, called _______________________; and (b) the attraction of water molecules

__________________________ that moves water upward in xylem.
19. Two other forces which aid movement of water in plants are ______________________
_____________________, which causes water to rise above ground level and loss of
water from the leaves, which is called ______________________.
