Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

Absorbing water from the soil
Xylem is transport tissue found in vascular plants. The function xylem is to transport water from the roots to shoots. It is also used to replace the water loss during transpiration and photosynthesis. The xylem sap has water and inorganic ions . The transport of water is done true passive process. Transporting water to the top of the tree becomes difficult that is why xylem is also condsidered to limit the height of trees
