Tree biology

Tree biology involves understanding how trees grow, function, and sustain themselves. They have roots that absorb water and nutrients from the soil, and a trunk made of strong wood that supports the tree and transports nutrients upward. Leaves use sunlight to make food through photosynthesis, producing oxygen as a byproduct. Trees also have cambium layers that generate new cells, allowing growth in height and girth. Their bark protects against injury and pests. Overall, trees are complex living systems that balance growth, resource acquisition, and defense to thrive in their environment.
