Systems Trees: Absorption of water and essential mineral elements occurs in the remote (distal) portions of the root systems trees of trees. These terminal regions are embryonic zones composed of actively dividing and maturing cells with each apex protected by a root cap. Root hairs, which are probably the main absorptive sites, likewise commonly occur in the apical regions. Subsequent to entry into the root, the water and soil minerals are moved upward through the conducting tissues of root and stem into the leaves.
Flower.—Trees, like herbaceous plants, produce flowers. As a consequence of several factors, however, such as remoteness from the observer due to the size of trees, unfamiliar form and perhaps color, and relatively short life, the flowers of trees are less familiar structures.
In a rustic garden the trees should be fruit trees wherever possible, or at least blossom trees of some kind. Apples, pears, plums, and cherries will all help to create the right atmosphere, as will nut trees such as hazel or almond. If there is space for a large tree, a Walnut might do.
