How does the pressure flow theory work to transport glucose around the plant?

The pressure flow theory states that water with food molecules inside of it moves through the phloem of a plant through pressure. This theory is meant to explain how food moves around inside plants. The pressure flow theory notes that pressure is created through water being pulled into the cells of the plant. The water cells are pulled into the plant when a diffusion gradient exists. This gradient creates a change in pressure, which forces osmosis.

Explanation:

the correct answer is b

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
