in solution. Hypothesize which of the following will occur through diffusion if the
cell membrane is permeable to glucose and fructose, but not sucrose?




0 I. glucose will diffuse out of the cell
○ II. fructose will diffuse out of the cell
○ III. sucrose will maintain dynamic equilibrium
○ IV. fructose will diffuse into the cell

11. Hypothesize why trees are able to transport water through water-conducting cells
from the roots to the top of the tree.
0 I. Individual water molecules adhere to each other creating columns that rises
up the tree.
○ II. Water’s high heat of vaporization turns water to a gas which rises to the top of
the tree.

molecules and provides the energy to transport water.

○

, ○ IV. Cohesion between water molecules and the adhesion between water and the
plant cells prevent gravity from pulling water down.
