![]() ![]() The tree has one tap root and many lateral roots which help to keep it stable in wind and snow. The roots gather minerals and water which are needed in the process of photosynthesis and for feeding the tree’s growth and development. Along the way the minerals, water and sugar stimulate the growth and development of the tree or assist in its reproduction. ![]() The sugar combines at the roots with minerals and water in the ground to move back up the tree trunk and under the bark back to the leaves to which starts the cycle of photosynthesis again. That sugar that is produced runs down through the tree, under the bark down the trunk and to the roots of the tree. As a result of the process to create sugar the by-product that the trees produce is oxygen-a vital resource for other living organisms, including humans. Leaves produce sugar as a result of photosynthesis which combines carbon dioxide and sunlight. The food for tree is produced through complex system starting with the leaves. Like some plants, trees are perennials and can live for many years. Trees are in the family of woody plants which have cambium, a special layer of cells that allow the tree to increase in girth and are self supporting with a single stem. Trees, like all plants, manufacture their food through photosynthesis. ![]() Trees, similar to all living things grow, reproduce, and respond to their environment. Search, discover, and learn all about trees! The easy-to-use guide, available on iOS devices, features 708 types of trees found in North America - with nearly 4,000 photographs, text descriptions to help identify tree species, and robust search functions to aid in species identification. ![]()
