When testing tonicity in Elodea cells, once Elodea cells were placed in distilled water, what did you observe? Select all that apply. Cell membranes pressed tightly against the cell walls. Cell membranes pressed tightly against the cell walls.
Many of the cells had burst. Many of the cells had burst.
Full central vacuoles. Full central vacuoles.
Many of the cells had become crenated. Many of the cells had become crenated.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
