Which statement best describes how water rises up the vascular tissue and through the leaves of a plant? a. osmotic pressure causes water to move upward. b. plant cells use active transport to pump water upward. c. adhesive and cohesive forces allow transpiration to pull water upward. d. hair cells act like tiny oars, and they push water upward.

The answer is C

Transpiration is the loss of water in the leaves. Because of cohesion (sticking to other water molecules), the water that is lost essentially "pulls" more water behind it, which pulls water up through the xylem of the plant. Adhesion (water molecules sticking to other molecules) helps attach the water to the walls of the xylem, preventing it from sliding back down the plant.

I hope that makes sense. If I can clarify or anything just leave a comment.

q: compare the parts of a cell and the cell as a whole to another common nonliving system (i.e., a car, a city,

a:

comparing this to the inside of a food building/company.

all cells are surrounded by a plasma membrane, which protects the cell from its environment, keeping toxic substances out of the cell. it regulates which molecules are allowed to enter and exit the cell.

regulates all cell activity such as cellular metabolism, and growth in addition to storing and maintaining the cell's dna for transcription and replication. determines what proteins to make.

contains the organelles; site of most cell activity

the place where ribosomes do their working activity.

builds the proteins.

prepares proteins for use or export.

responsible for breaking down and absorbing materials taken in by the cell.

maintains cell shape.

transforms one form of energy into another.
