Tree Trunks<\/h1>\n\n\n\n<p>As mentioned, tree trunks have 5 separate layers to them.\nThey are the outer bark, inner bark (phloem), the cambium cell layer, sapwood,\nand heartwood. Each layer has their very own purpose, but overall, the trunk\u2019s\nprimary job is to protect and support the tree. Look below to review each layer\nand what they do.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">\u2776 Outer Bark<\/h1>\n\n\n\n<p>Like a shield, a trunk\u2019s outer bark is there to protect the\ntree from its outside surroundings, including inclement weather, wildlife,\npests, and more. It also controls moisture, by both preventing excess moisture\nin the rain and snow, and retaining sufficient moisture levels during dry\nseasons. It also provides insulation in cold weather and protects against\nsunburn in the summer. <\/p>\n\n\n\n<h1 class=\"wp-block-heading\">\u2777 Phloem (Inner Bark)<\/h1>\n\n\n\n<p>The phloem, or inner layer of bark, is where food and\nnutrients are passed through the tree. This layer has a very important job, but\na very short lifespan. It eventually dies, turns to cork, and becomes part of\nthe outer layer of bark!<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">\u2778 Cambium Cell Layer<\/h1>\n\n\n\n<p>The cambium cell layer is interesting because it is the part of the trunk that grows. Each year, this layer produces more bark and wood as a reaction to the hormones being passed down from the leaves along the food pipeline. These hormones are called <em>auxins<\/em>, and they are very important because they stimulate new cell growth!<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">\u2779 Sapwood<\/h1>\n\n\n\n<p>Sapwood is new wood, and serves an important role as the\ntree\u2019s water pipeline, delivering water to the entire tree. And as new sapwood\nis created, the inner cells lose their vigor and turn to heartwood. <\/p>\n\n\n\n<h1 class=\"wp-block-heading\">\u277a Heartwood<\/h1>\n\n\n\n<p>Heartwood is the most inner part of the trunk. It plays an\nimportant role in balance, stability, and security for a tree. Technically,\nheartwood is dead, but it does not atrophy or decay (unless the outer layers\nare jeopardized). It is made up of a hollow, needle-like cellulose fibers that\nare joined together by a glue-like chemical called lignin. &nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Additional Parts of a Tree Trunk:<\/h2>\n\n\n\n<p>The pith is made of soft, spongy parenchyma cells, which serve the purpose of storing and transporting nutrients throughout the tree. The medullary rays are cellular structures found in only some tree species., and appear perpendicular to the growth rings. The growth rings, also known as <em>Dendrochronology<\/em>, appear one at a time, once per year, darker in the fall and lighter in the spring and summer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Get Professional Tree Care in Indianapolis<\/strong><\/h2>\n\n\n\n<p><strong>Call Complete Tree Care at 317-783-2518<\/strong> for professional <a href=\"https:\/\/www.acompletetreecare.com\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Indianapolis tree service (opens in a new tab)\">Indianapolis tree service<\/a> you can trust.
