Tree Biology and Life Cycle Concepts

The video explains the crucial role trees play in sustaining life on Earth by providing oxygen, absorbing carbon dioxide, and supporting the climate. It details the parts of a tree, such as the trunk, branches, leaves, roots, and bark, and their functions. The life cycle of a tree from seed to maturity is covered, along with the differences between deciduous and evergreen trees. Factors affecting tree growth and lifespan, including environmental conditions and human impact, are also discussed.
