Question

Dutch elm disease affects the function of vascular tissue in trees. A tree with the disease reacts by plugging the vascular tissue with gum. These plugs prevent the disease from traveling up the trunk of the tree.
a) If xylem tissue is plugged by gum, what other substances are prevented from traveling up the stem? (3 points)

Answer 1

If xylem tissue is plugged by gum, then molecules of water that are transported through the xylem are prevented from traveling up the stem.

What is Xylem?

Xylem may be defined as a type of vascular tissue in plants that operates the transport of water and liquefied nutrients from the root to the stem and across the whole plant or tree.

The xylem possesses specialized water-conducting tissues constructed primarily of thin, extended, sunken cells.

If the gum occludes the xylem tissue, water molecules are prevented from traveling up the stem.

Therefore, it is well described above.
