The trees could have turned darker due to environmental factors such as pollution, disease, or aging. Changes in soil composition, weather conditions, or lack of nutrients can also contribute to the darkening of tree foliage. Additionally, certain tree species naturally have darker leaves as part of their growth cycle.
the part of the tree that carries water from the roots is the phloem no,because in the science book it states:water moves through the XYLEM TISSUE up to the leaves so the answer is :XYLEM-TISSUE

The hardened center of wood is called the heartwood. It is usually darker and denser than the surrounding sapwood, and it provides structural support to the tree.
a.) SapwoodThe sapwood is the younger, softer outer portion of a tree that lies between the heartwood and the cambium (formative layer just under the bark) As comparatively new wood, sapwood is less durable and more permeable than heartwood.While a floor purely of sapwood may be beautiful and smoother than heartwood, the softness and permeability of the sapwood makes it expand and contract easily, which can cause it to warp in certain conditions. This weakness also manifests differently in various tree species; some have sapwood that is strong and durable, others have weak, soft sapwood that is not appropriate for wood floors. Many times, sapwood is graded higher than heartwood because it is smoother and less prone to knots and blemishes; the highest-grade sapwood is virtually free of any imperfections. Coloration of sapwood ranges from white to light and yellow blonde tones. HeartwoodHeartwood is the older, harder central portion of a tree. It usually contains deposits of various materials that frequently give it a darker color than sapwood. Denser and more durable than sapwood, heartwood is found primarily in aged trees.Heartwood is generally darker than sapwood, and doesn't have the same expansion and contraction problems that beset some sapwood. It makes a great wood floor because of its hardness and strength, and its resistance to many weather conditions. The hardness of heartwood, like sapwood, depends on the tree species and age of the tree.
Heartwood
The darker wood in the center of a tree trunk is called the heartwood. It is made up of older xylem cells that have become inactive and no longer conduct water, but provide structural support to the tree.
The innermost part of a tree trunk, known as the heartwood, is typically the oldest part of the tree. It is formed from older layers of sapwood that have become inactive.
