Roots anchor a tree and explore the ground for water and nutrients. Above them, the trunk supports branches and carries materials between the roots and the crown. Leaves capture light used in photosynthesis, while their surfaces also take part in exchanges with the surrounding air. These functions connect the underground and above-ground parts, so changes in soil conditions can eventually become visible in the growth of branches or leaves.

Tree growth involves both new extension and the thickening of existing woody parts. Young shoots create additional branches and leaves, while layers of new tissue can increase the diameter of trunks and older branches. Damage, competition, and available light influence the pattern. A bend in a trunk or a missing branch may preserve evidence of an earlier event long after the tree has continued growing around the affected area.

The seasonal appearance of a tree depends on its growth strategy and local climate. Some species lose their leaves during an unfavourable period, while others retain foliage for longer. Flowers, fruits, and seeds can appear at different times. These stages provide food and shelter for other organisms. Birds, insects, fungi, and small plants may all use parts of a tree without sharing exactly the same relationship with it.

Following one tree over a year makes gradual changes easier to recognise. Buds expand, leaves change texture, and shadows shift as the crown develops. A closer look may reveal insects, scars, lichens, or cavities that are invisible from a distance. Such observations show that a tree is both an individual living organism and a changing structure that creates opportunities for many other forms of life around it.
