The growth cycle of a tree is one of the stages of the life cycle of a tree and is the stage characterized by the development of buds, root tips and cambium. These are the three growing parts of a tree. The other stages are birth, aging and death.
During the growth cycle, the buds cause branches to elongate, and the leaves and branches that form the crown to expand. The cambium layer expands and increases the tree’s diameter and the root tips extend deeper into the ground to support further growth. Water and nutrients present in the soil are absorbed by the root tips and travel through the xylem to the leaves. The interaction of sunlight, carbon dioxide, water and the pigment chlorophyll that is present in the leaves allows photosynthesis to occur, the process by which trees and plants produce their own food. The food travels through the inner bark or phloem to the tree’s buds, cambium and to the root tips to continue the cycle of growth.
