DENDROLOGY

Detailed explanation-1: -Why is this happening? Wetwood-causing bacteria enter trees through wounds in the roots, trunk or limbs. Once inside, the bacteria produce gas within the tree. Pressure mounts, and eventually runny liquid seeps out through openings in the bark.

Detailed explanation-2: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
