Which of the following rows in the table best compares the function of a plant's xylem and phloem? (2 points)

row 4

row 3

row 1

row 2

Option B, Row 3

Explanation:

A xylem is a fluid conducting vessel of the vascular system of the plant. The roots absorbs the water from the soil and pass it to the xylem which then transports water to the entire plant though the capillary force.  

Xylem is made up of tracheary elements (TE) which die at maturity due to which a xylem vessel just act like a pipe through which water can flow.

While phloem is responsible for transferring food which is being prepared at the leaves. Unlike Xylem, phloem is composed of living cells though which sap is transferred,

Thus, option B (row 3) is correct

what do the different brain waves do?
